PWA Calendar & Media Upload Issues

Experiencing two very weird, not constant issues in the PWA we created using Progressier from Bubble. Randomly, the calendar dropdowns won’t open the year dropdown and just change to random years in the past when you press the dropdown input. File Upload just won’t open anything.

Noticed that when this issue occurs, you can see a faded dropdown and image options that float around. See image.

If anyone can help, would be greatly appreciated.
