Sometimes when healing a pet using the pet raid frame predictive healing acts up.
Here in my attached example picture it shows me healing two pets at the same time as a paladin.
Another error I've noticed, for example. Sometime if I heal the pet "Snow" predictive healing would show me healing the pet "Luh".

I've had the same issue but on the regular raid frames along with occasional gaps in the healing predicton bar

Could you take a screenshot of the gaps in the healing bar?

will do during my next raid night!

Please see if the just released 3.049 release fixes these issues.

I haven't seen any spacing issues on normal raid frames. But the problem still persists on pet raid frames.

Here is another image of the problem I am experiencing.
Here in this image I am a Paladin casting Flash of Light on a pet, it is showing me as healing 4 targets simultaneously.

Please see if 3.050 fixes this issue.

Closed due to lack of feedback.
