Date bug on Livecycle Form

Hello

Just recently we discovered something that looks like a bug on date fields. When I write the date 01.01.2017 and click Tab, the date changes itself to 01.01.2016. It seems to happen on every date field.

Here is an example:

after Tab or mouse click, to

I tested and found that this only happens when you write the first day in January. If I write for example 05.01.2017, then after Tab it stays like it was written.

These forms have been made using Livecycle Designer ES3.

Did somebody had similar problems? Is there a way to solve it?

Best regards
