So I just did my first attempt at adding a new platform, and it's commodities. Bouvard Ring, a platform in Badbadzist (System and station was listed, neither platform was. Though only one platform even sells anything). A few categories worth of goods at a time (Oh god, going through metals/minerals). Yes I'm V 4.2.1.0. Yes, I have verbose logging on.
Stopping to check for typos on the end result once I got down to metals, I realized it lists everything I had put in until then TWICE, with different timestamps. 120 minute difference each time. This has continued the whole way through.
The concept of this thing is really cool, and while I haven't used the existing trade data to plot out routes yet (I'm just checking out some areas that caught my interest based on silly names in my Cobra for later, before I buy a type 6), from the sound of things when this program works right, it works incredibly well. My main worry with this whole duplicates thing is that I'm ruining the database for other people.
So, on the one hand. I'm worried I'm screwing something up for people with these duplicate listings (that think another entry is always made exactly 120 minutes in the past). On the OTHER hand, the BPC refuses to acknowledge the existence of the station or commodities to me until I enter them in myself, so I had to finish the job if I want to be able to use the trade calculator to do its actual job for me and calculate trades. I figured if waiting, restarting the game and BPC, coming back the next day, waiting, restarting the game and BPC, waiting, and a platform STILL wasn't showing up, I'm stuck entering it myself regardless of how wonky it wants to be.
Because at a glance, no idea why it's deciding I've traveled back in time to enter things two hours in the past every time. I tried Deleting the "older" ones, but that deletes BOTH. (Delete, 120 minutes older than most recent Agri-meds... oh it killed both, time to add that again! aaaand it's duplicates, with one 120 minutes older). I sort of trailed off triple checking for number entry typos because of all these shenanigans.
I may stick to hand written notes when it comes to unlisted stations, unless there is some easy fix to this not shown in the OP (and the suggestion to delete extra entries a quick searched turned up, was for extra STATIONS. Plus deleting one commodity entry killed both). I grabbed this more for the fact it's supposed to auto sort data than find or calculate trade routes, so all the duplicate stuff that floating around is a bit awkward for that even if I'm not screwing something up for other people.
Unrelated QOL Suggestions: Don't make the system list reset to 1 i Centauri after entering price data. Don't switch it from a specific station to "Any" when it auto updates. Especially since I currently can't increase the auto update timer past 5 minutes (which I saw mentioned as "That's next patch). I hope the next patch also comes with an OP that has info beyond "Turn on verbose logging. Use the add prices button". Considering the launch readme points you to the OP and then you find basically nothing there.
