Collapsible Row Overriding the other product description

[MM91]

I created a collapsible row in the product description. I created the metafields for each section. After adding it to Product 1. I did the same steps and now for product 2, it overrides the metafields making product 1 blank.
Not sure what else to do. Even when I do the Collapsible Content, each product page has the same information. I am using the refresh theme.

This was super super helpful!!!! Thank you so much. 
If that was your YT channel, I subscribed.
I have another question, I have different collection pages but I want each banner to have a different color. I have tried different codes but nothing seems to work. Do you know how?
