Hammer coral issues or not? Need advice

[nightmarepl]

Hey guys, my hammer been acting up alittle weird last few days through our he months i noticed the stem “ hard part “ look like it’s fading away or getting chewed? The heads on top went from 2 to about 6 in about 8 months now perimeters are pretty good no issues i also noticed the heads on top gets a weird hole you can see inside I’ll post the picture. Please help me out

That far down the stalk I would think it's just dead skeleton- not anything that would be affected by "chewing". No idea what's causing it?
