Old projects showing updates

I logged into my account today to work on a project and I happen to see all of my old projects are now at the top of the list saying there was new activity in the project several hours ago to several days ago. They are all saying my account was the one that updated the project, but I haven’t touched any of the projects in months.

I’ve checked the commit logs and there is nothing.
I’ve checked under manage > activity and there is nothing new.

I’m not sure if this is some sort of bug, or if I should be worried that my account has somehow been compromised.
