Ho! I did not think to test like that! So, I'm on KSP 1.4.4 and the mods are the last one (reinstalling clean about 3 weeks ago). I just tested in English, the problem has disappeared. So it is the translation into French that is problematic. There is a manipulation that I could do to play in FR without the bug? (sorry for my English, I help a tranducer, but like the majority of French, I'm bad in a foreign language ...)
Edit :
And I discovered the same problem with the minerals.
