Yes, they will still be able to see everything.
You may want to try contacting them about it. Patrons sometimes don't mean to decline pledges, I had one patreon that patreon refused to let any of his pledges through, so he would just send me the money on paypal but remain on patreon because he still wanted the extra stuff (it was a commission slot as well, and he wanted to make sure he was still getting those every month) then one month patreon decided to do ALL of his past pledges at once and took 700$ out of his bank and bounced his checks and pretty much fucked him over. So he was screwed bankwise and I had to refund 700$ for him.
