[Neos] Double content collections

[David Walchli]

BTW, you can remove teaser from your current site by export/import your site. Not sure if it is best practise, but it worked for me...

Export with 
/flow neos:site:export  --package-key <your package-key> --tidy

"tidy" formats content.xml so that it is easy readable

Then edit
Packages/Sites/<package-key>/Resources/Private/Content/Sites.xml
and remove all "teaser"-nodes and import again

Don't forget to erase your site before importing:
/flow neos:site:prune --package-key <your package-key>
