Tahm Kench Eating Tibbers and Daisy Bugg

When I used Tahm Kench and tried to eat Annie's ult (Tibbers) and Ivern's Ult (Daisy), Daisy nor Tibbers was not in my mouth, but my W went on cool down. I could clearly see that I am red (which means I have ate something), but when I press W again, I spit out nothing.
