Dependencies and expansion level

I’m trying to create a mod for sc2. I’m using dependencies for wings of liberty as it’s closer to the result I’m aiming for. No other dependencies are used. When I try to play it every game gets set to legacy of the void expansion level. The only way I found to make the game play as Wings of liberty is to change the expansion level in preferences in the editor.

It seems expansion level overrides dependencies. Even if it is set to deafult and only dependencies for wings of liberty are used it will still set the game to legacy of the void. Why is that? While I have not yet started manipulating data (if this could have any effect) it is still disturbing, vexing and annoying that the mod doesn’t play with what dependencies are used in the editor.
