So I’m having an issue with the date picker using Dynamic Actions/Javascript. I’m using 18.2. I have a date picker that I only want the user to be able to select Mondays along with disabling the rest of the week. For whatever reason the date picker icon is not aligning correctly. It shows like such in the screenshot below

As you can see the icon is out of alignment along with the icon being slightly different.

This is what the date picker is actually suppose to do, which is only allow the end-users to select Mondays on the date picker and disable the rest of the days.
Below is the code that I used under Dynamic Actions

$("#P12_START_DATE").datepicker("option", {beforeShowDay: function (date)
{ return [date.getDay() == 1 , ''];}
})
