Excel 2016 Pivot Table: Crazy phantom month.

I have my Excel 2016 source data with 81 Rows and 8 Cols. I also have an Excel 2016 Pivot Table. The 1st column has the months of the year, the 2nd column has the Sum Of the Total Sales for each month.

There are 2 problems:

1) The month of January is missing!! It's like a Phantom cracy blank month took over the month of January, and I do have data for the month of January, as follows:

1/15/16  Central  Gill, Ty       M  Binder                46    1.88    86.48  Off. Spply

1/22/16  North    Ruiz, Juan  M  Scissors            110    5.00  550.00 Off. Supply

1/25/16  Central  Day, Eva    F   Staple Rmvrs       67    1.06    71.02 Off. Supply

I have also sorted the month column in month order too.

2) There is a strange data or entries as depicted in the image. Unknown how that data <1/15/2016 and <12/22/2016 got in there.

Any idea on how to correct those two strange situations?

Your feedback will be highly appreciated and welcomed.
