Enemy clears ward in tri-bush without sweepers/control ward

Experienced a bug in game where the enemy can clear my ward without using sweeper or control ward. I have linked a replay.gg replay of the game where you can see the enemy clearing my ward at least 5 times without using sweeper or control ward.

11:35 - I think this is the problematic ward or sweeper that started the bug. I warded the tri-bush and Morgana immediately sweeped it

13:10 - I ward the tri-bush again

13:20 - the ward is cleared by jinx with no sweeper/control ward

13:50 - warded again

14:40 - targeted with no sweeper/control ward

15:00 - cleared with no sweeper/control ward

18:20 - cleared with no sweeper/control ward

19:08 - the ward is cleared but with a sweeper. (Maybe it's only the further most right spot of the tri-bush that's bugged?)

20:40 - cleared with no sweeper/control ward

22:15 - sick janna save and morgana q dodge ;)

I asked in all chat whether they can see the ward and they said they could and that it was probably a bug that should be reported.
