Window not showing up after adding any Open FX

Hi there,
This is something we have experienced for a while and isn't specific to Resolve 17.
Does anyone else have an issue where once any FX is added to a node, they have to switch off the Window tab and to another and back to the Window tab for the window to show back up? Strangely this only happens when any Open FX have been added.
Obviously not a big issue by any stretch but wanted to see if this something other users have experienced and if there is any way of fixing it!
Thanks a lot
