HydroponicsMAC on (Bug?) Old YouTube video displayed on Channel page despite the correct video being set in Channel Settings | Video ID

Hello,

I entered a YouTube (URL) within the Video ID setting a few weeks back, all worked fine with the video visualisation appearing on both my Public and Private channels. 

However if I now change that URL (and press save) the new URL is saved if I look at channel setting again but the old video still remains on the channel pages.

I have tried removing and re-adding the visualisation on the channel pages but each time it adds the old Video ID which isn't even set in Channel Settings anymore.

I've blanked out the Video ID in settings, tried toggling between YouTube and Vimeo, logged out and logged in, reset the browser cache but nothing works, always the old video gets added.

• Public channel: https://thingspeak.com/channels/128093
• As you can see the video visualisation currently displayed is the old one (which doesn't exist on YouTube anymore)...

Is this a bug?  

Thanks.
