Button doesn't appear but can be clicked

Hello, im having Issues with Swift Buttons in Tab Bar View Controller. The first View Controller works normally but the second not. On the second View Controller are Labels loaded directly but Buttons not. You can click the Buttons which appear after being clicked or click a different View Controller and then Click back on the main one.

The Buttons are also working when they are invisible.

On the simulator works everything fine but on my physical iPhone 11 not.

Thanks for help

If you keep on not showing any code, you'll keep on not getting any help…
