Exercise selection on 2nd block of Low ISF 4 day

Hi. First thanks for all you folks at BBM do. Much appreciated. I’m currently on week 4 of the Low ISF 4 day template. I changed some of the exercises in the template, but noticed that it only changed them in the first block. Is this how it’s supposed to work or am I missing something?

There’s another exercise selection tab for Block 2 that you’ll have to use.
