Display says low on oil, dipstick shows normal level ??

[NorwegianRT]

Hi all!

I just got my 2012 RT SE5 running after winter storage (in my garage).
Battery was a bit low, so had to hook up a start help.
It came to life and sounded a lil rough at first, but that is normal for any engine I would think.
Then the "low oil" showed up in the display, so I put a lil bit in. Still there, so I added a lil more. Still there.
I thought it was strange, so I put dipstick back in and checked. It was way over the max mark. So I managed to take oil back out and have it back to normal level.
Warning is still there, so I am thinking something electric?
Anyone had this issue before??
