Hey there! It looks as if there is a bug for Cap Sparkles indestructible buff.. ability states the buff lasts for [10.96] seconds and then refreshes again after [42.01]

However, it seems to be bugged, or maybe just worded incorrectly in abilities?
The way it reads currently leads me to believe that as soon as the cooldown ends, the indestructible buff reactivates.
“This ability can be activated again after a [xx] cooldown”
In the video supplied, the indestructible buff cooldown lasts for actually 47 seconds (not 42) but then doesn’t actually reactivate until 53 seconds, and it only reactivates when I throw a heavy attack.
Has this been addressed? Haven’t seen anything about it on here while searching.
Thanks
