Mame only shwing a few games.

I have official mame 0.159 set up with mame 0.159 split rom set and chds.

When I run mame or mame32 all the games get detected and I could play them.

But I only see 300 some games (including clones) in gameex. I have tried many different mames and configuration other people suggested in other posts but same results.

I attached my mame settings. What am I doing wrong?

Any help would be appreciated!  Thank you.
