I made a small improvement. Updated #chapter4 in CSS ID field for the section where I wished to place my anchor. Next, I updated Link field on CTA button with /mypage/#chapter4 and it worked for me. The redirection helped display starting from top of section.
I have a weird issue with that. It works fine if loading from the same page, but when you click the menu item from another page, the anchor loads under the header nav bar. Why wouldn't it load in the same position but from another page? I put the anchor widget in the right place and it works ok when being clicked from the same page.
