I ran into the same thing. In the end it was the tasmota log result not aligning with payload speed. So if you can get the two align you should be ok.
You should be able to look at my rule2 and make adjustments.
You also have setspeed=x in your payload commands so you would need to make an adjustment.
For giggles I’d try
Rule2 on Event#SetSpeed=1 DO Backlog…
