Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
Yes, the 30 you have to change to 60 is the one you see in the lie 380 in your screenshot.
Could you share your website (in the Sensitive Data section) so we can check by you are getting that issue in the web version of the analyzer?
Looking forward to helping you. Thank you.
