The Assets app currently still shows the previous actions before we reworked the DAM. While we still use originals and variants, they are largely non-visible and we avoid using the terms in the UI except in some specialized interfaces we plan to deliver for in a release after 5.0. Because these actions are still available, but the underlying framework has changed, executing them leads to errors and is confusing during demos (hence the "blocker" status of this issue).

Please do the following to fix this:

• remove the actions "select master" and "select all variants"
• rename the "create variant" to "duplicate asset"

The original is no longer shown, hence the "select master" action can't work any more and indeed causes an error.
