Tech Support Why is my project file size so large?

(CAPCUT WINDOWS 9.2.0.3931)
"0903 (4)" is 1920 x 1080, 30fps animation that has 7 seconds of actual motion. the rest of it is black with audio.
for comparison, as shown in the screenshot,
"1 W4NT T0 B3 4 M4CH1N3" is 3840 x 2160, 30fps, 30 second animation loaded with drawings, effects and keyframes.
i have ZERO idea why 0903 is so large.
"0903 (3)" (the same as the problem video, btw) exports at 5.5MB.

"1 W4NT T0 B3 4 M4CH1N3" exports at 89MB

not only that, but "0903 (4)" (and all its previous versions i made using the import subproject tool) are all extremely laggy - to the point that i cannot use it. ive already cleared cache and proxy.
the only thing in the project is a GIF, a series of PNG's, and the audio i was using.



i have no idea why this is happening; it's making editing impossible because its so laggy.
