MAMEWorld Forums - MAMEUI & IV/Play - Mameui64 0.220 Bug whit configuration ?!??

Hi friends... i need to ask this question about all system configuration.

Om my pc i have a little configuration of roms..... i setup mameui64 whit a default config:
For example i enabled the "cheat" enabled the "low latency" and some other option.

Now the problems... if i load a system configuration like if it's a ROM or it's a BIOS the default configuration i have previously setted it's not read and it's not applied.

I need every time to set every single games what need to lauch and i don't thinks it's normal.
From CFG folder i leave all out... i have deleted all .cfg file except the default.cfg file but it's not resolve the issue.

It's a bug ?? How i can resolve this ??
