I’ve just downloaded and installed Bambu Studio 2. In all my presets the speed is displayed as if they were default profiles but the actual speeds when printing the model are the speeds that I have set when I customised the profiles.
There seems to be a lot of problems with 2 unfortunately. some people have said they are going back a version from github. Some have had success (me for one) with renaming the folder that holds all the presets to .old and allowing a fresh reset of Bambu Studio.
