Are you keeping your pearls in your inventory? If not, that might be why they don't show up. I know people have been having issues since they made it so you can keep them in satchel/sack/case and still have them equipped.
Try putting them in your inventory and relog, should force an update to the lscom within a few hours.
It has absolutely nothing to do with pearls. LS community is setup properly, you can join the established shell and that all works. What isn't working is FFXIAH's webcrawler that scans and parses that data. This is either due to something broke inside FFXIAH or some modification SE has done to LSCOM that is making in incompatible, either way guildwork is pulling all the data properly.
