[WOTLK] Halion's Corporeality Percentage Doesn't Show

Hello, I don't know where else I have to ask for help so here I am.
Basically the corporeality's percentage in my UI doesn't show. I once installed Titan Panel and I thought it was the cause of the issue. However, after I uninstalled it, the percentage tooltip still doesn't show up. I even reset my UI by renaming WTF and Interface folder but the issue is still there.
Please help me solving this issue because I have done every thing I do like deleting cache and resetting UI. Thank you in advance.
