'Add to Cart' and 'Order Now' buttons seem to shift?

Hi everyone, this may be a dumb question with a simple solution, but my ‘Add to Cart’ and ‘Order Now’ buttons seem to move from time to time. I don’t know if my linked third party apps are influencing them or not, as I try to delete all the added code after removing an app (why this is not automatic when the addition of the code is automated already is beyond me - literally save a copy of the old code, add the new code and if the user deletes the app it should reinstall the previously saved code, this is just a suggestion as not everyone will think to save code before installing an app so automating it would help greatly), but I know I might end up missing something somewhere.

I don’t know where the issue is, but my purchase buttons not being aligned and overlapping other text is getting to be very bothersome. Has anyone else had this happen?

UPDATE: my ‘Order Now’ button has disappeared, but things are still misaligned.
