Removed Upfront Plugin - still asking for update

Good morning everyone,


I have noticed that Upfront is still asking for an update, although I removed Upfront from the plugin list. It is NOT showing in the WPMU Dashboard on the site, neither in the plugin list.

REMARK 1: due to the workload here, I didn't find time to disable all the other plugins since this site needs to be life at 2pm - so in a few hours. Sorry for that.
REMARK 2: In the 'theme/plugin name' list above, Upfront is also not available so I had to choose WPMU DEV Dashboard...

kind regards.
