Cannot deploy namespaced Apex classes in unlocked packages to org

[Banuson]

Hello,

I want to update a class from an unlocked packaged installed in my org with namespace MyPackage.

I am able to retrieve it, but if I want to change anything (adding a comment for example) in that file I am not able to deploy. I want to deploy using metadata API. The apex class file is : classes/MyPackage__myClass.cls with MyPackage namespace. public class myClass { // class content } But when I try to deploy I have this error message: File name mismatch with class name: myClass

Another issue is that in Org Browser: files shows with doubled namespace for example: MyPackage__MyPackage__myClass.cls Retrieve using the org browser throws this error: Entity of type 'ApexClass' named 'MyPackage__MyPackage__myClass' cannot be found

Currently I can only edit the class from Dev Console or Setup>Apex Class.
