No issue with unmatched tires, that only counts when tires on the same axle of a car don't match. Front/rear non-matches are common in all kinds of vehicles, bikes, cars, trucks, etc.
Odds are the RD is a bit out of trim. First make sure it's all the way forward to the stop, then fine tune the shifting/trim with the cable adjuster.
BTW- I don't know if it made a difference or not, but if you get in the habit of always shifting to high to remove or install wheels it'll be a bit easier, and you'll never have to guess which sprocket to put the chain on.
