[Animation CIT] CIT animations (.png.mcmeta) not showing in-game

[Ascacos]

Description of Issue

CIT animations specified in the cit.png.mcmeta don't appear to be working, switched back to 1.14.4 stable build and it worked perfectly

Steps to Reproduce

1. I created a custom texture .png sheet with 5 frames (32x160px)
2. Re-texture any diamond helmet with aqua affinity (in .properties) enchantment to new texture ( .png) file
3. Specify animation order and framerate in .png.mcmeta
4. Checked in-game, frame 0 displayed nicely but no animation.
5. Switched back to 1.14.4 version of optifine, and the animation works perfectly

OptiFine Version

1.15.2 Optifine HD G1_pre13 Ultra

Installation Method

Standalone mod via .jar installer

Additional Information

Tried many different methods of declaring the frame order in the .png.mcmeta file, have not yet attempted to obtain desired result using .JSON animation files

@Ascacos does this still occur in the latest preview?

Hi @naeqirelle2020, yes I have just tested it again now with with preview version:
OptiFine 1.15.2 HD U G1 pre23 and only a static re-texture could be observed, and the animation worked fine in the 1.14.4 build.

in the above image, it is only taking the first frame. here is my .properties and .png.mcmeta files
blueberry_helmet_icon.png.mcmeta
{ "animation": { } }
blueberry_helmet_icon.properties
