I'm also having the same issue as everyone else. Extra retraction and E0 command between Start code and print code. It seams to be related to the retraction settings in the profile menu! With retraction enabled it's automatically adding the extra code with the retraction amount matching what ever youv'e set in the profile. Doesn't matter what printer you have as I've loaded several with there default settings in tact and its always the same in the code and writes this extra line that matches those settings. It's a real pain as it means the print doesn't start till that retraction is made up via normal print extraction distance, it then dribbles out and F£$s up the print. Below is a code example same as everyone else's. ATM I'm just deleting this line of code manually from the file in a text editor (notebook!) but that's a bit of a pain!
So any other suggestions people?

i have an ender 3 v2 and cannot pick 2 extruders from the drop down in machine settings, as others say.
has anyone been able to either modify the json file or find a way to edit the applicable cura nozzle settings in a backdoor manner?
search and replace is not a good option, as i modify the retraction and feed rate frequently depending on what im printing...
thanks for any help!!
