Pre-filter vs post filter in join recipe

I am using a pre-filter criteria in join recipe and then using a left join but somehow it seems the joining is taking place on all dataset instead of dropping the rows according to the pre-filter comdition but its working fine if I am using the post join filter,I am confused why in the first place the pre-filter isnt working.

Operating system used: windows
