Multilingual feature of Haiilo / COYO for Custom Plugins / Widgets?

In the context mentioned above, we (as third party plugin provider) have become aware of a problem regarding multilingualism.

Your product basically allows multilingualism for your widgets. Unfortunately, this does not seem to work identically for 3rd party plugins / widgets. E.g. a poll once created in a content app of a page is copied 1:1 during translation of the content app, but as soon as you change the translated version, the "original" is also changed.

Is the issue of multilingualism for custom plugins not possible in this way, or not possible at all?f
