CSP trunk system ID's the same as Suffolk County NY

Does anyone else have a problem when receiving the CSP trunk system. I receive a non digital trunk system from Suffolk county NY that uses the same talkgroup ID's as the CSP. I have to lock out several of them so I can just listen to the local CSP talkgroups. One of them comes up as : CH 38 E-Disp 2 Motorola ID 03248.

I have tried setting my scanner to the closed mode so it only scans the talkgroups I have programmed but many off the CSP talkgroups are the same on the Suffolk county system.. I am using a Pro 96 digital trunking scanner.
