Yes, that is a know limit in the current Hex Grid command.

Remy wrote a macro a while ago which circumvents the problem. I'm attached it to this post together with a sample map.

I don't think any new symbols have been added to the collection since it was released.

To fix the drawing style not loading, open the template file Annual Par Lindstrom BW.FCT (in ProgramData/Profantasy/CC3Plus/ unter Templates/Cities/Wizard) in CC3+ and under File >Drawing Properties set the correct style.

I suspect your map is simply fairly large and CC3+ uses lower res bitmaps for display to save time.

Click the Display Speed button on the left toolbar and set your bitmaps to always display at very high resolution.

Hm.. there does indeed seem to be a problem, if you start your map index with 1 (or a higher number) instead of zero. Same happens with letters if you don't start with A. Curious that it has never been reported before.

I don't think this can be fixed quickly, as a workaround for now, start your grids with A and 0.
