Abnormal Pulsing Xenia?

[Kit with Cat]

Hi everyone! I just recently entered the hobby and have been looking for an answer but haven't found it yet so am hoping to pick all of your reef brains about this.

Recently had the pleasure of getting some nice pulsing xenias from Blue World Aquatics (who are super awesome, Taylor and Lyndsy you guys rock!) but they fell off of the rock and landed "face first" into the sand and had been there for about 8-10 hours.

One of them I stuck back on to the rock by impaling its base with a toothpick and that xenia seemed to behave strangely after, so I got another xenia from BWA again.

Again, it accidentally fell face first into the sand, and having had a poor experience with the first, I glued it back onto the rock and elastic banded it so it would stay.

Now both Xenias are open, but instead of closing all of their "fingers" at the same time, it closes it one at a time. Is that weird? or is that normal and they are just on their way to recovery? Prior to falling face first into the sand, the xenias behaved just like they did when I saw them at the store, which is they open and close normally like every other youtube video of pulsing xenias. They aren't shrivelled up, rather they are really long and extended, but don't "pulse", but just wave around movine one finger at a time.

Anyone have any experience?

My tank is 2 months old, 90G, two clowns, one regal blue tang, two cleaner shrimps, 14 Snails, 10 Hermit crabs, 5G refugium with Chaeto, 1 Rena XP3 Filter rated for 90G, 1 Eheim classic 2215 Filter rated for 90G, Protein Skimmer (can't remember what brand.maybe remora?), 90 pounds of live rock, 1.5 inch of sand bed
0 Nitrates, 0 Nitrites, 0 Ammonia
All other corals (green button polyp, green star polyp, assorted zoos, frogspawn, hammer, leather, rick) are doing really well.

Thanks in advance!
