Sometimes when you export, animations duplicate - probably due to the fact it doesn't show pre-existing animations on the animation tab? When i import ones i made before (So i can edit them again) it usually struggles to find them in the editor when you "View in editor"

Some animations will be split into a normal and a setup animation in CPM. Also Blockbench currently cannot import CPM animations, but it still keeps them in a hidden property.

aaah that makes sense. So you can make them in blockbench, but they don't go back in when you save and reload.
