t-datepicker issue December 2019 to January 2020

[HelmsArt]

Hello there.
I am using your t-datepicker plugin.
There's a problem with the plug. You can see it in the demo.
When Calendar is 1, I can't switch to January if I choose a date from December.
I think this is happening now, from 2019 to 2020.
I'm also sending you the same function.
Please help me with this problem.
Because it matters to me. Thanks in advance for your interest.
