Fairing is missing from tech tree & VAB

[OldLost 28]

KSP: 1.4.3 (Win64) - Unity: 2017.1.3p1 - OS: Windows 10  (10.0.0) 64bit

Problem: In career mode, Part AE-FF3 Airstream Protective Shell (3.75m) is missing from tech tree and VAB/SPH. I have completed the tech tree; all nodes are unlocked. The part is not present in the VAB in Sandbox mode either, but craft with the part can be loaded and launched. Any idea where the problem comes from? Any easy fix for putting it back? TIA

procedural fairings has a script that automatically removes the 2.5 and 3.75 meter fairings and changes the 1.25 meter one to work like their fairings (does not seem to effect the 5 meter MH fairing base).  I know it's rather annoying, since there's some times where the stock fairings are still useful, and it breaks any rocket that uses stock fairings.  To get the stock fairings back, delete PF_Squad_Config.cfg.

Did you check ckan for updates?

I cant seem to see the real problem here.

Can you make a subassembly of just that part?

Thanks Cap. I'll give that a try. Stand by...

Following up: Cap's fix worked. Thanks. I never would have figured it out on my own.

Wow, thank you very much. I was wondering why all stock craft files I download have missing part and can't launch. I never thought its because procedural fairings mod.
