Oil on dipstick does not register correctly

So, Scotty...I have a 2014 Jeep Patriot 4wd with a 2.4l engine...I changed the oil, manual says it requires 4.5 quarts of oil...the dipstick still shows short, so I added to 5 quarts and it puts at the add line as if it needs another quart.  So, I thought maybe someone installed the wrong type of dipstick, but I checked the code number on the stick and checked some parts stores and it's the correct one!  I check the tube and its bolted into place! What gives?  Could the wrong length tube have been installed?  Did some come with bigger oil pans?  It's a 20inch length stick from tip to where it seats!  Can't figure this one out...help!

Start the engine, and rev it up to about 1200 RPM. This will ensure the filter, cooler lines etc. all fill up with oil.  Peek underneath at the filter and drain plug to make sure they aren't leaking. Turn off the engine for 10 minutes. Then check the level.

So, I did this...picked my wife up from work, still says one quart low! Somethings just not right!

"The best time to
check the engine oil level is about five minutes after a
fully warmed engine is shut off. Do not check oil level
before starting the engine after it has sat overnight.
Checking engine oil level when the engine is cold will
give you an incorrect reading.
Checking the oil while the vehicle is on level ground and
only when the engine is hot, will improve the accuracy of
the oil level readings."

Did this as well, still shows short 1 quart in stick, even though I put 5 quarts in, when it's suppose to have only 4.5! Still crazy, never had a car do this!

Great argument here for OEM parts.

It's the stick. Someone added an aftermarket and it's calibrated wrong. I bought one for my car that was wrong too. I just had to know it was off and make my own marks on it.
