SV04 firmware 1.1.0 buggy: Right print head stops printing 2 seconds too early

Hello. In mirror and copy mode, the right print head stops moving for the last 1-2 seconds. It stops and does not go to the “X=0” position (mirrored). The left print head continues to work, ends the job correctly and moves to “X=0”. The right extruder also stops working for the last 1-2 seconds. For every print job. Hasn’t anyone noticed that yet?

On the photo you can see that the extruder is no longer working either: A thread because there was no retraction. When do you fix the bug? I’ve had this problem for a year now. The latest firmware is from early 2022.
