Panasonic KX-TA824 No caller ID on call waiting with Hunted lines 1

problem with Caller ID on call waiting. When talking on line and a call come in as call waiting. System unable to show the call waiting caller ID unless you hangup the first call and than you can see the new call ID.
Upgraded firmware to latest.
I tried under "maintenance Console" [900]caller ID all Caller id check also for Call waiting but it will not work. Spectrum is the service provider and client has 4 lines, all acting the same ... can see only caller ID for first call and not for call waiting.
Just to note client had before RCA 4 line phones from Staples and they were able to see caller ID for call waiting on same provider(spectrum / TimeWarner)

The client use KX-T7736 PBX phones,
I would like to mention the client has 4 lines that Hunt from 1 to 4 and than to voicemail. If call come on line1 callerID is okay,Than call2 will go to 2nd line but caller ID will show still the original callerID of Line1. (phone will not show caller2 ID and stay to show caller1 ID).
If I will take all the lines out of HUNTing mode all work and call waiting will show ID. I think the issues are due to Call Hunt.
