JassNewGen Tileset Issues

[Silverfish423]

Hello everyone, so I'm having an issue in my SoA map where even when "use custom tileset" is checked, I cannot add any new tiles unless essentially half of them are removed. The Modify Tileset window says that I am using a Total Texture Space of 24 and -11.
If anyone could help me with this it'd be much appreciated, thank you!

Go to Extensions > Edit tileset.
Don't save the map after selecting the tiles,close the map after selecting and pressing ok.

Didn't work :/

EDIT: maybe this is the issue...after I close it (and it doesnt save) how should I reopen the map?

Don't save after selecting the tiles. It auto-saves
