display state sometimes does not activate

Hello there,

I encounter quite regularly that i cannot switch between display states (in assembly mode).

Sometimes it helps to restart Solidworks(2021 SP.0 & SP.1) but other times there is no change.

Edit: Another workaround I found is to open the assembly in another display state.

There's only a bug I think,  the list doesn't show all available states.

actual:                                                   list in "open" menu:

Does anyone know a solution for this?

Thanks in advance!

Heino
