UI does not appear correctly in-game

I am trying to create a HUD that is centred at the bottom of the player’s screen. However, when I created the HEALTHBAR (Red) and the ARMOUR BAR (Blue), as well as any other widgets, they do not stay in the correct place on the HUD.

I understand that this is most likely an aspect ratio issue, however, I would of course like the UI to look the same on all aspect ratios.
I was wondering if maybe I could anchor the progress bars to the grey box and if this would even help.

If anyone has a solution please let me know. Thanks for your time.
(UE5 btw)
