Is your 450 on uptodate Firmware? I thought this bug got fixed by Garmin.
The problem is, it makes no sense to change those POI that are affected, because they need to be included in the map for searchability (else you won’t find hotels under hotels).
If there are any unsearchable POI, that also show this problem, feel free to list them, cause those one could change for the better. (those huge symbols are awfull and block the important details).
