Time Format Not Displaying and Table Grouping Problem

I noticed a problem where some devices doesnt display the formatted date and time. this was when i used the Experimental Date Format column and put it on a template column. however, some devices only see it as ( - ) instead of (x - z). so i decided to change the approach with Math Column,

but now a second problem occured, my table collection grouping doesnt sort from A-Z. targeting my template column to the original Date & Time column does the same. so the Group Sorting only works when I use Experimental Date Format.


any idea whats going on?
