Build UI is invisible

Hello Everyone! I am having an issue with my build UI. I am still relatively new to unity, so I’m not sure what could be causing it. In my editor, in play mode, all my UI seems to work just fine. It all appears on time in the right place and the right size. However, in the build, when I collect the flowers, they do not show up until the level is reloaded. I am including a video so you can see what I mean. The pink key at the start is set up just about exactly the same, and it always shows in the build like it’s supposed to. However, the red and blue flowers never show up when collected. I have to go fight an enemy and come back to the overworld for them to appear. The green flower though seems to appear in the UI just fine every time. I don’t have a clue what could be causing this, any help would be greatly appreciated. Thanks!
