Iron shovel animation broken

Since I bought the iron shovel I can’t press and hold Y to dig continuously.

It gets interrupted after the first digging animation and I have to press Y again but then it’s not getting interrupted again till the hole is dug up fully.

So it looks like: Y → Dig 1/3 → animation stops(bug here) → Y → Dig 2/3

Edit: I’ve been playing in the part before Sacrament only, if that helps only, so I’m digging starter holes.

I believe it only doesn’t play the second animation, but still digs the hole. Bar of the hole gets low where the second animation should play. I never take my finger off the button and I’m able to dig it continuously with success.

I’ve tried it 3 times. Animation doesn’t continue unless I press Y again.

Actually I’m wrong and @Senator is correct. If you keep the button pressed, it has a great delay because the animation for the 2th of the 3 animations is entirely missing but the hole does lose its health as they mentioned.
