rdweb CustomRdpProperty setting problem windows 2012 RDWEB app publish

Hi,

i was published apps through windows 2012 rdweb

I was added the below on powershell and its worked fine

import-module RemoteDesktop

set-RDSessionCollectionConfiguration -CollectionName "collectionname" -CustomRdpProperty "redirectcomports:i:1"

and after i was added another script , check the below

import-module RemoteDesktop

set-RDSessionCollectionConfiguration -CollectionName "collectionname" -CustomRdpProperty "session bpp:i:16"

now change the session changed to 16 but the redirectcomports automatically changed and it become redirectcomports:i:0 why its was happend like this?

kindly guide me to set it properly

Regards
