This option from immediately fast has to be disabled to edit individual hud components

hud_batching: Improves the performance of the HUD rendering by submitting less draw calls. If you experience issues with HUD elements, try disabling this optimization.

alternatively just blacklist it which is what I did
net.raphimc.immediatelyfast.feature.batching.BatchingRenderLayers

I think it should be mentioned somewhere in compatibility section
