Incomplete filter list and strange behaviour

[CarmenM]

Hello all,
I encountered a strange situation in EXCEL on a computer that has Office 365 x64 installed.
When i want to filter after one column, date type, the list with the unique values from filter it's incomplete. There should be only a few (aprox 10 items). It shows only half of them. If i sort the data in DESC way, the list contains the other half. I tried to remove the autofilter and selected manually all the values, in order to recreate the filter list. The same behaviour.
I thought maybe it was a problem on that computer. So i opened it on another computer with the same Office365. Nothing....it's doing same. I tested on a fresh installation of Office365 x64 on the third computer. The same situation (what??). Then i tested on my computer, where I have Office 2013. The filter list it's complete, it contains all the necessary information.
Why it's behaving like this? Why in Office365/Excel 2016 this list it's incomplete and in Excel 2013 the list it's full? Bellow you can find screenshots with the problem. Do you have any clue about this? I searched everywhere but without any solution.
Thank you.
