Text field problems Xcode

I’m creating an app and need to make a signup/login page. I added a background using a picture and a zstack and on top I have the text and text fields. The text fields are showing up but not allowing me to add padding as well as there is no title text showing. Please help.my code

Did some more testing to find out that this happens whenever I use a textfield over an image. Not sure if this is a bug or not but it seems to be because as soon as the zstack is removed everything works.

At last ive discovered the issue, the text fields are extending way out of the canvas. Ive fixed the width of the textfield as a temporary solution but still looking for a way to fix this relative to the screen rather than the background as the field extends to the size of the image. Let me know if you can help as im just starting to use xcode!
