Midi sync not steady

Hello,

I’m sending out midi clock from a Modor DR-2 into the 2400. The tempo is jumping up and down on the 2400. Tempo on the Modor is at 129. The 2400 jumps from 129 to 117 on the screen. Firmware from Apr 28 2023.

mine does that too. I think it’s just the display as the output from the 2400 is fine and solid
