It isn't about being right or wrong, it's about removing extra mods to rule out any possible issue, personally I would say delete and redownload the esui mod and any other mods that affect the ui, download and install ffnx. Make sure it's a fresh install of ff7 if it was a fresh install skip that part, only use 1 ui mod other than maybe avatar/portraits if you don't like the ones in the stock user interface mod. make sure stock user interface version of esui is turned off unless your not using it.
