Hi there,
I went to your website and made all the options of the Box shadow 0, also did that for the Bar below the CTA and now it is working ok.
Kindly do not add additional questions here as it is getting very hard for us to follow up. Kindly open up a separate thread for each question to help us identify the problem easier and focus to serve you the best.
Thank you for your understanding and cooperation. Merry Christmas.
