As a quick patch on the wound, we’ve disabled 1 tab and consolidated product information of different product types (collections) in 1 tab. All relevant single product page templates still have 4 tabs, all with relevant product information respective to the collection it belongs to.
Examples in private.
The problem is supposed to be fixed in et-core-plugin/app/models/customizer/builder/class-customize-builder.php and included in the next theme update (now 2 updates ago I assume, as we skipped 2 and updated to the last in 1 go)
