Multiple Issue while merging from Sketch to a design Studio project

After merging the export from Sketh (Aurora_Concept) to my Design Studio project (Marchesini training),

I got those following unexpected behaviour :

     - All aliases has been removed

     - Handler of slider is back on off position (too high, not on top of the slider)

     - In cluster Style settings : they were 4 times a dualClusterIcon component -> replaced with the each default one ( Darkmodeicon, Lightmodeicon, Singleclustericon)

Note : Change done on Sketch move the back button from right hand side to left  hand side on Seat Settings and put from merged to child the heating arc from SeatHeatingSettings component
