Like yourself, I prefer everything in same location as executable, so correct answer is; either open ui.ini and set historypath to the root in your mame folder and/or using the Internal UI access Configure Options/Configure Directories/DATs and set this to mame root folder as well and it works.
MAME is very customize-able and you don't need unnecessary directories or files in locations that isn't to your liking
