Build - Make module/project uses wrong build type

Question

As long as I used android studio 3.1 everything was working fine. But after the recent update to 3.2 I see following behaviour:

• calling "build"/"make module" leads to execution of Executing tasks: [assemble]
• calling "build"/"make project" leads to the same, assemble task is executed as well

Before the update I was able to exectue the correct assemble task (like assembleDebug<...>).

Does anyone know where I can correct this? Can I somehow check which task is bound to those menus and edit them? I have this problem with one project only...

Currently I have to manually execute the gradle task to get what I want, menu entries seem to be broken...

Setup

• I am using flavours
• I have selected a build variant of debug type, all my modules are set to debug as well:
  • apps build variant: devWithoutTestWithAccessibilityDebug
  • all other modules build variant: debug

Current solution

I use my own gradle tasks for my most common development build like following for now:

task runDev (type: Exec, dependsOn: 'installDevWithoutTestWithAccessibilityDebug') {
    commandLine android.getAdbExe().toString(), "shell",
        "monkey",
        "-p", "com.my.app.debug",
        "-c", "android.intent.category.LAUNCHER", "1"
}

What I tried

Clean project like following:

• delete ALL *.iml files
• delete .gradle and .idea folder
• delete all temp files
• import project again
• sync project with gradle files
• create app run configuration again and start it

Still I end with the same result...
