Buddy heater flame on one side?

Hey all,

I'm super excited to ice fish again so I'm making sure my big buddy heater is working properly.

It seems that the left plate has a much more pronounced and uneven flame while the right plate seems to be orange and working correctly.

I'm using a propane tank and the Mr Buddy hose and regulator. The issue also occurs with a 1lb tank as well.

Has anyone had this issue before?

What might cause this to happen?
