Ships Ekvirs Martuuk FSD Level 3 unlocking issue

Hey all,
I'm having trouble unlocking the 3rd tier of FSD mods at Elvira Martuuks workshop.
I have the mod Increased jump range both level 1 and 2 complete but i cant access the level 3 for this mod.
I get this message :
" To craft higher grade blueprints you need enough engineer reputation and to have completed all lower
grade blueprints of the same type"
All the lower grades are done for this mod, if i try to buy more of a different type it will remove all the increased range mods i have installed and thats not what i want to do .
Would doing remote engineering have affected this?

Any help would be Greatly appreciated,
