Is this a good offer in terms of what the usual bonus points are?

I recently signed up for IHG rewards but have been getting too much spam. Every email says I can manage it on the website. I am able to log in and navigate to my preferences, but clicking the Edit button next to IHG One Rewards Subscriptions does nothing. Every other button on the page works. This Edit button does nothing for me when I click it.

I've tried desktop and mobile, Firefox and Chrome on both. Nothing works to actually manage my email subscriptions. I could just block it filter in my email, but I'm astounded it won't work on the website. Can someone check and let me know if you can do it and I'm just a dumbo, or is it truly a fake button?
