Why won't my UI Batch?

Unity Engine
1

Hey guys!
I know batching of the UI is an often discussed issue. I’ve read the Forums but still haven’t found a solution to why my UI consumes about 25 Draw Calls (see attached Image).

I’ve activated the Sprite Packer inside the editor AND manually built an Atlas using the Sprite Editor. The UI only uses this Atlas. I’ve got no idea where to start to reduce the draw calls.
Thanks for your Help!

Overdraw of images + Text = DrawCall Madness

have you enabled Dynamic batching?

don’t make any difference, for UI elements, overdraw, even invisible parts, objects over objects, will generate a lot of draw calls.
