MSL Media pool not showing in pool list

Hello,

I am using DP9 with 9.01 patches having cell manager on windows 2008 R2. I have a media pool name MSL_FREE_POOL which is the free pool for all other pool to take the media and after expiring the retention period it will recycle the media and keep it in MSL_FREE_POOL.

Now on slots of devices few media I can see showing its media pool as MSL_FREE_POOL but when I go to pool and expand it, it doesn't show me any MSL_FREE_POOL there?

Any help how can i get that.

Regards
