Garlic Plant anim frames glitch

Just something that caught my attention today, the animations of the Sprout and Medium states of garlic plants are moving strangely :

(The Sprout one is barely noticeable compared to the Medium one, but after seeing it I decided to look at all other plants, they're all perfect except these two)

The issue with the two of them is when the anim loops, first and last frames are quite different if this can be of any help.
