Problem changing channels

Hi there. I have had WMC installed an running fine on my Win7 rig for a few years now. Yesterday, I installed ServerWMC and connected a Win10 client to it via Kodi 17.1. Everything seems to work fine except for one thing. When I attempt to change the channel, it only works the single time after I start ServerWMC. After that, even though Kodi reports I have changed to another channel, the previous channel keeps running.

Here is a link to the log:
