Hello

This can be reproduced in the ProjeQtOr demo.

1) Reset the view in components versions.
2) disable visibility for "real entry into service" and "planned end"
3) change with of the column "version name" at the column itself
4) select Linux OS2
5) click on the plus of the "composition - List of component versions used by this version
6) Change the column width of "ID" and "version name"  in the "Component version" popup and close it (without adding anything)
7) change to components (or any other view)
8) go back to component version --> id with and other column with changed.

Similar effect happens when the components are stored and the component version list updates.
The view then has to be reseted always which costs time if the filters have to be setup again

Regards
