Hmm, did you check it in ? I don't see the changes to lcm.sch

By the way, when changing a sheet, it's better to use "Save" instead
of "Save Project" (or clicking on the floppy icon). That way, only
the current sheet is saved and the commit won't look as if
everything else had changed as well.

Out LCM module doesn't have such a signal, so I guess it's fine
without it ;-) The only thing similar is DE, which is correctly
connected to VM (which secretly becomes VDEN for TFT).
