[GAMEPLAY] Tahm and Bard combo bug

yesterday night i was trying to make some combo with Bard and Tahm abilities ,then I found a few bugs.

1. Tahm can't eat an enemy champion and carry them go through Bard's tunnel 2.When Tahm ate Bard , Tahm will do damage after Bard comes out
2. This is the most serious one. when Bard use ult on Tahm and Bard jump in to Tahm's ult before Bard's ult hit Tahm ,after Bard's ult hit Tahm while Bard was inside Tahm, the ult of Tahm can't function nomally. Tahm can still use his ult but he can only eat his teammates without teleporting . In this case Tahm's ult will refresh in a short period of time. In the rest of the game it keeps like this I've tried this over 3 games and this has happened each time
