I'm getting the following exception while loading a Filter Set for editing:

Rename
Maybe the Filter Set has a Metric that you since removed? If you can send over the IndicatorFilterSets.txt file in your User Data Folder to support@wealth-lab.com it might be helpful.
This morning, when I came back to WL, the problem was not happening anymore.
I then did some tests and I think that figured out why this was happening:
I was trying to edit the filters when an optimization was still going on (after I press Stop, the process goes for a while "Completing Last Running Threads...").
Perhaps the user should be blocked from (trying) editing the filters while an optimization is still going on.

Thanks, this is helpful - was able to trap the error and suppress it.
