Sometimes it does not show up for up to a day or so.  Sometimes sooner..  It will do it though..  Hang in there!  

Thank you both.  
 
However, I do want to say that I realize it will take time to show up in my "store front", but, it was NOT making the changes at all in my "Arrange Gallery".   So basically, I was not able to rearrange my gallery at all.  
 
I was using the "Change position of cards with keywords" section and typing in the word Christmas.  Then I was telling it to change the card position to start at number 100.  I pressed save and none of the Christmas cards were moved to position 100 in the "Arrange Gallery".  
 
Then I've been getting error messages as I was trying to make changes this afternoon, so something was whacky.  
 
I just tried it again now, telling it to change my Thanksgiving cards to a new position, and it made the changes immediately.  Also, that change showed up immediately in my store and I was checking Artist's Choice on my store front before.   So something was not working this weekend for me.   I don't know what was going on but it is working now.
 
Thank you for your time and assistance..     Sher
