Video Schema duplicates when duplicating product / not updating

Hello,

We usually duplicate products in order to create a new one, that way there are less changes to make.
But we just found out, that if we duplicate a product that already had a Video and then we delete this video from the long description and then we add another video. The result will be 2 Video Schema added.

We though that when deleting the information on the previous video, Schema would also update and delete that information, but it is not working that way.

For example if you go to this product: https://www.chilevapo.cl/vaporesso-gen-80s-kit/ you will see just a single Video in the Long Description.
But when you check Google Schema: https://search.google.com/test/rich-results/result?id=q4PWg15KB5nShiGdbApcpQ&hl=es you will see 4 Schema videos.
