New clause in 2023 Chicago lease

[Julie George]

Hi all - I've been using the standard Chicago Realtors Association lease for years and noticed they added a new section in 2023 to the bottom of the first page that now says you need to be a member of CAR or that the transaction must be facilitated by a CAR member. I'm neither and I'm sure most private landlords are neither as well. Is anyone familiar with this new clause ? Will the lease be "invalid" if we continue to use it ? Thank you!

For reference, here is the attachment I found that someone shared on a FB group.
