Ubiquiti equipment doesn't limit frequencies by region the way Canopy equipment does, so they have to know to turn off frequencies they aren't allowed to use. One of our competitor's got into trouble with Industry Canada for jamming weather radar accidentally in precisely that fashion.
So it may be that they have permission to use that band, but it's equally possible that they don't have permission and don't realize that they have to turn off those frequencies. Up here, we have a public database of licenses, so if you've got something similar you might be able to verify if they have the necessary grant.
