Help! dynamics data and preview/published pages don't match up.

Hey!

I’ve 2 problems with my dynamic pages.

I want my workshops in this repeater to sort on the length of time (the pink ribbon). So that the customers see all workshops that take 2,5 hours first, and then all workshops that take 5 hours.
I’ve tried via the editor - dataset settings - filter & sort but it won’t work.

I want to edit the pages that this repeater links to, but for some reason this doesn’t work either.
As you can see in the print screen I selected courier new as font in black, but it appears as another font in light grey…

Can someone tell me what I do wrong?
