XF 2.2 Reactions show "deleted member" but pop-up full list shows correctly.

xF v2.2.4
As per screenshots below, a post's Reactions shows "deleted member" but when clicking to see the full list, it correctly shows all users. All are active members. Is it a bug, or a cache that needs rebuilding?

a post's Reactions shows "deleted member" but when clicking to see the full list, it correctly shows all users.

If anyone else comes across this, there's no mass rebuild for the post reaction cache, but you can just add and remove, or remove and add, a reaction on the post and it will rebuild the cache for that post, fixing the issue.
