BUG: All sorts of inconsistent problems with manually created waypoints

These problems exist for me with the latest release of XCTrack and also the beta. The issues seem to be inconsistent though, and I'm not able to figure out why.

Cannot edit waypoint (which I created manually earlier). I press the edit button, but it opened the "new waypoint" page: screen-20230624-083021

Cannot always delete a waypoint: screen-20230624-083319

When external Bluetooth GPS configured (Syride Nav XL), but not connected, can't change to DMS position entry: screen-20230624-181522

External Bluetooth GPS configured, but not connected, but internal GPS enabled. Entered coordinates in DMS units are totally mangled. Also, validation of elevation field is inconsistent, sometimes a value of 0 crashes the app (not pictured), other times it's fine, other times it's not. screen-20230624-181706
