Can't Remove Collection from Web Version

I added a couple of collection that were supposed to be temporary during sorting. The were removed from the app but not the web version. How do I remove the collection tabs?

It is possible to remove them if you have Connect, the web-app.

But I checked your account and you have the CLZ mobile app. It is currently not possible to sync “removals” of collections from the CLZ mobile app to the Cloud.

I can however remove them for you manually.

Would you like for me to remove the collections with 0 items in them? I see 3 in your account.
