Jitter Buffer errors

FreePBX 13.0.190.7 , Asterisk 13

I recently enabled the SIP jitter buffer and we are now getting the Warnings below with every call. Is this a bug or is something wrong with my setup? If I turn off jitter buffer, the warnings stop.

Is this just on my system?

Slightly side note - Did you notice if the jitter buffer affected your SIP call quality?

No. Sorry.
