In using .pickadate() to show the calendar the dates reverse from right to left in the calendar

[Janny2018]

the screen shot is as below

the code is part of an asp.net MVC project (semi-finished product), and the project will access database,the View file(*.cshtml file) is in the attached files (item.zip)

I found though the screen shows the reversed result, but in the generated HTML code (after screen show up I press F12 and copy whole element to save as a html file, pls refer to the attached file --> generated.html.Code.txt) , the result will be correct.

I don't know what happend, can someone help me to figure out the problem ? Thanks

item.zip

generated html Code.txt

I found something may cause this problem, but I don't know why ? refer to the following ,

why the value of the direction attribute is rtl ? does this mean right to left ? and what in my code causes this ?
