add-ons/environments not visible (e.g. stress analysis)

[Giancesa]

in the company we have three stations but only on one is visible in the "expression analysis" environment menu while the others do not. It seems to me that all are set to have the additional modules, and I do not understand why only on one see.
I attach the images of how the two stations present.

Thank you.

I saw that in the string where you see inventor in which folder fishing files for this function there is a slight difference: on the names there is a sign "~" in the station that has the calculation program while the other is not. allego images
