Safari history dates wrong & not removable
More frequently than not, I find an entry in the Safari history that is dated 1/1/2000. Considering this is OS X 10.11.1 and the CPU wasn't made until 2012 and the system clock is correct, obviously the history is incorrect. Typically, the entries in under this date are from sites that have some sort of log-on or form entry. Unlike most "real" histories, they don't "delete" when the entry is selected and the "delete" key is pressed. They can be removed by right-click & remove.
This is a persistent problem, once removed this "random" history will return. The issue started only after updating to OS X 10.11.1.
My question(s) are why is this happening, and what can be done to stop it.
MacBook Pro with Retina display, OS X Yosemite (10.10.5)
