Unexpected parameter in response

I’m using git master. When I try and refresh a parameter via the GUI, I get the error Unexpected parameter in response; parameter="Device.CaptivePortal"

Here is the console log:

2021-10-15T20:08:47.221Z [INFO] ::ffff:172.27.242.42 404A03-VMG4927%2DB50A-S190Z28001661: ACS request; acsRequestId="17c859240410000" acsRequestName="GetParameterNames"
2021-10-15T20:08:47.510Z [WARN] ::ffff:172.27.242.42 404A03-VMG4927%2DB50A-S190Z28001661: Unexpected parameter in response; parameter="Device.CaptivePortal"

And the debug log is at Unexpected parameter in response - Pastebin.com

If I refresh the given parameter again, everything works fine. If I refresh the page, the data is retrieved from the CPE.
