All hippotranslation:id with "null" value makes a cluster & results in wrong linking of translation on folders

Please follow the below steps with hippo gogreen project:-->
1.Go to hippo Duurzamm-->"Producten" folder in content perspective.
2.Choose translation option from context menu.
3.Unlink from translation folders & click Ok button.
4.Now go to "News" folder in Hippo Go Green.
5.Unlink from translation folders & click Ok button.
6.check once again the translation option in news folder .
7.You will see "Hippo Duurzaam/Producten" ,language:Dutch now linked to the "News" folder.
8.Same happens to the "Producten" folder."Hippo Go Green/News" , language:English is linked.

1:--->So behaviour in step7,step 8 is not correct as hippotranslation:id becomes null when translation is unlinked on "Producten" folder in step3.
2:-->And when translation is unlinked on news folder then news hippotranslation:id becomes null as well.

So both the null ids made a group & tries to link to respective folder.
So this behaviour is not correct.A new translation:id should be generated when translation in unlinked on a folder.

Please check the screenshot.

Check the hippotranslation:id in console at "/content/documents/hippogagroen/products"
