CST script built objects dissapear

Hello , i have used 4 different script files to construct my antenna.
but if i save and exit the project then when i reopen the project then the "dicrete ports" dissapear,
or if i put my antenna inside a PEC box and change one parameter then the whole script built structure dissapears.

what needs to be done in order to keep the objects which were built by scripts from dissapearing?

Thanks.
