Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
I have just tested this on a site running ACF Pro 5.7.13 and Rank Math but I could not reproduce the error mentioned. Can you confirm that you are running the latest version of both plugins and that this issue can be reproduced when all other plugins have been deactivated and while running one of the stock WP themes?
Looking forward to helping you. Thank you.
