HELP WITH TILESETS IN VX ACE

Hello, I'm sorry, I am new to this and my last forum I cannot find. I previously had problems with transparency in tilesets(I am making my own from scratch in firealpaca and am not finished, I have only made the wall and a window). I have tried events, they are too complicated to use and clutter up the important events, plus the doubling of putting a desk, and a lamp does not work. I have tried exporting the A tileset files from the resource manager and just using the dimensions there, testing the size, but making a window for a wall still doesn't work unless I make the background tileset of the window the same color of the wall. I have the trial and will be buying it pretty soon, I do not know if there are restrictions on the trial, but nothing's seemed to work. I will apply photos to show what I'm seeing. I don't mind making new field types, it's actually what I planned to do to keep each map in it's own category, but I have yet to find a solution to my problem. Any help is immensely appreciated. Thank you for your time.
