GameEx is stopping in the middle giving mame games a category from catver.ini

Hello,

 

i updated my Mameui64 to 0.169 after that i updated all the files gameex is looking for in its mame settings in the data folder (F:\GameEx/DATA/).

There i updated     Category.ini, catver.ini, Control.ini, history.dat, nplayers.ini, mameinfo.dat      to 0.169

then i update my gameslist in gameex

the games from the first to the 1242 game has now a category displayed so "mermaid" as the 1242 game in the list is labeled as " Sports / Misc. " but the next one "metafox" (nr. 1243), has not a category ( must be " Shooter / Flying Vertical ") and from there on until my 2526 game ,as the last rom, are not giving categories. so half of the games from "metafox" on don't have a category

how is that possible? what have i done wrong? why is game ex stopping in the middle with labeling the games with categories?
