Setting anchors in BP doesn't seem to do anything. What am I doing wrong?

So basically I call an existing widget inside another widget, scale it to 0.2 (I’m going to be scaling it later based on DPI manually and adjusting my positioning accordingly) and while I can happily in UMG Editor move the widget around in its parent as desired it doesn’t seem to want to update its viewport location in blueprints.

The documentation is obviously no help at all (Set Anchors in Viewport | Unreal Engine Documentation) and searching for tutorials on youtube and in forums or menu guides is absolutely nonhelpful.

Any ideas? :?

Thank-you for your time in advance. You guys are great
