htaccess redirecting first subfolder only.

With all plugins deactivated and default theme the only active theme only the first subfolder of 301 redirects in htaccess change. So https://staging.trainingtutorial.com/solidworks-tutorials/solidworks-2021-training/sample-lessons/wrap-path-and-guide-curve-2021 is supposed to redirect to https://staging.trainingtutorial.com/solidworks-training/solidworks-2021/professional-modeling but it redirects to https://staging.trainingtutorial.com/solidworks-training/solidworks-2021-training/sample-lessons/wrap-path-and-guide-curve-2021. This has really got me stumped. Any help would be greatly appreciated.
