Went up a step in upper body overnight

I'm new to this started last week, had one week of the old UI. Yesterday I wend in and checked what was on the schedule, I took a screen shot. Today I check and all the upper body exercises had been bumped a step. I was able to do them this morning. Just not sure why the change overnight.

 

Sounds perfect. I was under the impression the exercises only changed on a weekly basis.

This works out great for me.
