But the license doesn’t expire until November 2018

That is indeed strange since I can also find only one license that expires in November.
Maybe you still use another or old license?
Could you try to deactivate the license and activate it again with your current license key?
If you still have the problem after that, please contact me at firstname.lastname@example.org
I tried to activate your license on my environment and I can indeed reproduce the issue.
This is a bug on our side so I will make an issue for this and create a fix for the upcoming release.
Will it be ok for you to ignore the notice on your website until the next release?
Otherwise, you can (temporary) disable the notice with the following filter.
