Not redering multiple files, and others

Hello,
I have just updated to Video AI 6 and am unable to render multiple files. my typical workflow is to open multiple projects tweaking each and clicking export for each project. The resulting files are incomplete but play well until that point. Less of the files render the more I “check in” go to the Export Que for each (which also seems to switch which files are rendering).
I have also noticed that the Export Que may list multiple copys of a file but even with “All sources” clicked it only displays one video.
I am unable to find the setting to repeat or Loop a previewed section of a video, has this been removed?
After waking from sleep or just a screen power down (I have just set my system to not sleep) the window is often larger than my screen and may or may not contain anything in the large grey window. I can minimize to the task bar and bring it back but it will still be the same grey, if I let the computer shut down the monitors again it might resolve or might take a few cycles of this to resolve (it is still rendering).

The looping feature is set when using In/Out markers and rendering from In to Out for a preview.

We do not recommend exporting multiple files at the same time within different projects as this can cause conflicts in the export queue.

The display resizing and producing grey windows is new and I will send a note to the team about this to see if they can sort out what is going on there.
