Flame Breath issues

Very frequently when I use Flame Breath in Endgame especially after I just used it, it shows it is on cooldown (it shouldnt I used it for 10+ seconds and it should be ready again) and when I use it again im buggy mid air with no animations but still do damage. Seems like visual issues.

Also the tool tip or the skill might be bugged in scaling. I pick Physical Damage nodes in the tree but it doesnt seem to scale the skill or not get converted to fire damage from the ability?

"Converts 100% of Physical damage to Fire damage" in Flame Breath description
You should pick fire damage/elemental damage instead of physical damage

I've made a reddit post containing a video on this issue:
