Hi Dan,
Since update to TDL 7.0.4, I can't switch to one of the default filters (A-F) via the drop down list anymore. Changing between my customized ones (0-2) works fine.
I have a shortcut defined to clear all filters. This is still working and is giving me access to the default filters. I then can switch between the default filters. However, as soon as I've chosen one of my customized filters I can't switch back again to any of the default ones.
Limited access to internet and testing environment for about a week, therefore can't provide more info/ screenshots etc. at the moment.
