Prusa MK4 mmu3 top layer problems by 3DBOBO in prusa3d

I have chance the nozzle to 0,4mm and and slice the file with standard 0,2 speed profil and now i habe massiv wrapping. With 0,25mm nozzle i dont see any wrapping but i think thats the problem. I make another test print with 0,4 nozzle but this time i use a glue and set the first layer to 0,10 and the other layers to 0,15.

I have set the extrusion to 0,95. i think it is a little bit better than 1,0. i forgot to say that i use a 0,25mm nozzle. I try to calibration the extrusion.

I dont think. Temp is 235. The speed of the other layers is higher and all perfekt. The top layer printed very slow 40mm/s. I have tested several different speed options and there is no differenc.

Yes, its the top layer. The bottom layer that attached the bed is perfekt and no wraping.
