Error: Unknown or bad format (PD)

Your software
My Mautic version is: 3.2.5
My PHP version is: last supported
My Database type and version is: last supported

Your problem
My problem is: the emails have apparently (as I can saw) random sending errors

These errors are showing in the log: mautic.ERROR: CAMPAIGN: Determining interval scheduled failed with “DateInterval::__construct(): Unknown or bad format (PD)”

Any ideas guys? Thanks a lot
