Squarespace is inserting the wrong AMAZON ASSOCIATES ID into AMAZON BLOCKS

Site URL: https://www.showmemystyle.com/home/show-me-my-eco-style-no-more-plastic

Added my ID a few weeks ago - worked like a charm. Created a new post with new links today and a squarespace ID is being inserted instead of mine. Any ideas? 

Link with correct ID https://www.showmemystyle.com/home/show-my-style-the-mandalorian

Link with incorrect ID https://www.showmemystyle.com/home/show-me-my-eco-style-no-more-plastic

https://www.amazon.com/dp/B07VSLDZJ6?tag=squarespace0a-20&linkCode=ogi&th=1&psc=1

Help text says that I should be able to change the ID and it will update all links. Doesn't work. 

Also -- the Amazon Block creator might be broken since the links are so much diff from the correct vs incorrect one.

Any advice would be very much appreciated. 

Add an Amazon Associates ID

To ensure you're properly credited for Amazon's Associate program, add your Associates ID. After adding your ID, you won't need to use Associates links in Amazon Blocks because our integration creates the links through the blocks. If you change the ID, every Amazon Block on your site will update to reflect the new ID.

To add your Amazon Associates ID:

1. In the Home Menu, click Settings, click Advanced, then click External API Keys.
2. In the Amazon Associate Tag box, enter your Associates ID.
3. Click Save.
