Fixed!
Thanks Aerosys! 1.5.8 is working!The windows are in the same screen together 😎🙏🏼
I also discovered an error. It appears the MK_UICustomizer.js and the the VisuMZ_1_Battlecore.js plugin are in conflict.
I updated some sections of my code. Can you try again?
I tried the version 1.5.9 The error message of the plugin conflict is different
