I have two Mac (one 10.12.6 and the other 10.13.x) where Launchbar is losing the icons.
So if I use command tab to switch apps in Finder - all running apps show the correct icons.
If I use control-space several times to activate launcher (control space is my shortcut for the tool) - some of the icons are replaced with a generic icon. Not all the icons are generic and when I cycle through them - some draw properly when I select them and go back to generic. Some just don't show the correct icon at all.
Is there a way to rebuild or debug this? It's not functionally bad, but it's very disconcerting and I'm pretty visual so I switch to the app more on the icon than the text.
