Is this PMD? I was away for work for 4 days
The clam location was at the other side I think it had been stung by my elegance so when I’m home I quickly shifted it in the morning now it’s night time and it looked like this

Looks to me that it might have been in decline for a bit now. There is "newer" growth but not that bright white growth ring on the shell you want to see. Its been some time since I have had clams but the siphon is gapping and the mantle is pulled away from the shell (could be from sting) doesn't look healthy. Sorry.

I don't think this is pmd, as mentioned, there's not a lot of new growth and it looks like the other clam barely has new growth as well. You have to introduce the pathogen from another clam, any new additions?

It looks like you have some black mesh? That can block a lot of light from getting through. The squamosa doesn't look happy and I don't see a lot of significant growth on the shells (from what I can see in the pics). What fish do you have and how long are your lights on?

Keep an eye on the tangs and angel, if you have any nippers, they will most likely be any one of those. I'm not saying a fish is picking at the clam(s), but going forward, look for culprits if parameters and lighting are in check.

Depending on the "gobies" also. I have seen people call certain blennies gobies and vise versa. Some blennies are known nippers.
