If you have a Wanted Call and Filters>>QSL Membership Options>>LoTW member selected, the wanted call will NOT alert.
Perhaps the Filter section should be ignored for any wanted calls, mostly since many of those rare (wanted) calls may not have Internet access or use LoTW. If No QSL Filters is selected, the grid is filled with everybody, including what you are looking for, which makes it hard to find what call alerted you.
A current example is the 13 Colonies Special Event. They do not use LoTW, but if you have that for a requirement, then none of them you have listed as a Wanted Call will be announced. If you deselect it (set to No), then the grid is overrun with calls.
