Image poster block button displaying too small

Site URL: https://www.themuddymermaid.co.uk

Noticed an odd display issue with my site today. The buttons on the 3 x image (poster) blocks on the home page are displaying really small in all browsers. When I edit they are the correct size and then shrink back when I save.

Any suggestions as to what might be causing it?

Thanks.

Playing with the font sizes in site styles seems to have fixed this issue. However the buttons within image blocks appear too small in mobile view, is there a way to adjust these?

Try adding this to Design > Custom CSS

body.image-block-collage-dynamic-font-sizing .sqs-block-image .image-block-outer-wrapper.design-layout-collage .image-button-wrapper a {
    font-size: 20px !important;
}
