Sir please do video on retrograde effects in progression every one has confusion about give some clarity on that

What if the planet got retrograde dosha in D1 and after some years the planet got retrograde in progression do that retrograde get cancel or not ? And also as you said planets occupied stars which are occupied by Rahu and ketu are able to retrograde dosha,suppose Venus got retrograde dosha what if other planet which is in Venus star still it gets retrograde dosha?
