If you have the setting Disable Sleep Until Charge Limit enabled then what you describe is normal behaviour. I am told by the developer that when charge up to or down to the charge limit the impact of this setting is to disable both the screen saver and sleep modes.I use "Aldente Pro version" I do not understand why when I put it in charge the display never turns off, although I have set it in the settings to make it turn off after 5 minutes of inactivity. how can i solve this problem or what should i select to turn off the display while charging my macbook pro?
If you want you display to turn off then disable this setting though I do not know whether computer will continue to charge or not, it depends on your settings.
