Smart smoker issues

[Wopper]

Hey guys. Just upgraded from the big chief to the smart smoker. I have done a few things and have also run some temperature tests to see how the unit holds its temperature.  Anybody with this unit have the same issues?
Probe 1 suspended from top about halfway down.
Probe 2 on lowest rack
Heres the results:
1)Time 10:48
Set 250'
Actual 253'
P1 251'
P2 260'

2) Time 10:58
Set 250'
Actual 226'
P1 194'
P2 199'

It takes another 15 mins or so to get back up to Set temp then begins the drop again.
I understand there should be a drop but 55-60' degrees same like the unit is losing massive heat somewhere. The internal one obviously doesn't fluctuate as much because it's on the wall.
Any comments. Thanks in advance!

Everything seem normal to me unless I'M missing a detail or 2 but the digital works this way or mine at least  ;)

I just got the same smoker and had the same temperature changes.  When it does that what is the actual meat temperature?
