Can't revert Synchonize UI include mask to default behavior

Today I was playing around with include masks in the Synchronize UI and took a little bit before getting the hang of it. One of my attempts resulted in no files being identified as changed, but I was able to create a new mask that worked. However, I can't seem to get rid of the broken mask, even if I delete it from the system registry. Because of this I also can't return the tool to its default behavior of no mask at all. How do I do this?

The default transfer settings are configured here:
https://winscp.net/eng/docs/ui_pref_transfer

I see that and have found that. My broken mask is there and I can't seem to get rid of it. I can't make it not the default either. I would like to clear all masks but I don't seem to be able to, even by deleting the entries in the registry.

Make sure you are running only one instance of WinSCP.
Make sure your configuration storage is really registry.

Select the the Default transfer setting preset. Click Edit. Clear the file mask. Click OK. Click OK on the Preferences dialog.

If this does not work, please post screen recording evidencing the problem.

This seems to have worked, thank you! I could have sworn this is exactly what I tried to do before but perhaps there was a second instance of WinSCP running. Thanks again.
