Is there a way to uncheck this setting in the export sprite sheet?

doing the ‘split layers’ I get this. idk if im doing it wrong cus it renders both in the same png

and about the ‘by rows’ it works in this particular case, but i’m just showing one animation for simplicity, with all the animations the space wasted is huge compared to packed.

btw in this image, I did some changes, thats why this time the number of frames changed a little, I still get 20 frames out of 30 in the original one, but 22 in the other (this time I used gradient colors).

something to add, in the first post, I made a pixel check of every pixel in both sprites, to check if the silhouettes where the same, and they were identical (just checked if the pixel was transparent or solid on both), I didnt do that in this second one, cus my workflow is kinda weird so just so you know that maybe its something weird on my end that is causing some unexpected behavior.
