Redirect On – Mobile Error Page Speed Insights

With Rank Math redirections on – errors appear on Page Speed Insight for mobile. Switched off there is no problem. I toggled all the options on and off with no change.
There are two pages that are being redirected – but the error still shows on a page other than those that are redirected.

For the page speed there is no figure given just a ‘?’

Here is the pasted result;
