Status effects glitching in inventory

I was testing out the water breathing potion and i was in creative mode. I went into survival and when I went into the inventory screen, there was a status effect box there but the name "water breathing" and the time wasn't showing. (It was blank). When I went back into creative and went to the inventory, i could see the status effect normally. However, when I started to search something in the creative menu, the status effect started blinking.
