Garmin map not displayed properly

My set up:
1. Garmin map produced by Garmin Content Creator, using codepage 950, and all polylines, polygons, and points styles are customized with typ (meaning I do not use any of the Garmin default style). Finished maps work fine on oregon 300 and 550.
3. Smartphone: Xperia Z, using OruxMaps 5.2.3

Method:
map directly copied into external micro SD and opened by offline map selection

Bugs:
1. all polygons and polylines labels appear as question marks, viz ???, and all POI labels disappeared
2. most of the polygons with customized style cannot be displayed, and appear as white background

I shall send you a link to download one of my simplified maps to illustrate the bug, please take a look and see what can be done. Thank you very much.

try v5.2.4beta.
