After removing the local used USEW flag 'sasl' ufed removed the [X] but left the '+' as seen in attachment #1 [details] Reproducible: Always Steps to Reproduce: 1. 2. 3.
Created attachment 61280 [details] screen dump of ufed
That's not a bug. The + means that currently, that flag is enabled (yes, it's true that ufed doesn't take modifications to /etc/make.conf while it's running into account). The cleared X means that that flag will be disabled after saving. make.conf isn't updated until after you choose to save. If you feel this is not clear enough, I'm willing to update the documentation if you can suggest improved wording, though.
