@erblis - do not use special characters (like “<” or “{” or ") inside the schema-review field like this and put this as custom code inside JSON script (Google it - not so simple to solve this idea).
This for example " convert to ==> ".
One way is to use a simple number field (Min 0 - max 100) and use this field for the dynamic data.
The idea

microdata
Anyway, your schema is missing. It’s hard to solve this by JSON-LD before body.
For list of reviews - You should use microdata because “no way” to add a collection of reviews (more than one object) inside webflow custom code.
Anyway the idea of microdata on WB is more complex (Maybe write me in private).
