Rogue Concealment Bug

During combat, using Concealment initially works as intended and gives stealth, but when it runs out or I use an attack to break stealth, the invisibility remains visually. So enemies can still see me, but my gear and clothing cannot be seen and I am still translucent.
When I teleport somewhere, it fixes it, but still an annoying bug. Anyone else having this issue or know if something specific is causing it? Thanks.

EDIT - This bug is intermittent, forgot to mention that.
