Deleted a parent "Nest collection under" but child collection still maintain it's nest-under

[mwa85]

Hi everyone, I have a problem with data migrated from LastPass where that was converted "fine" but with a wired naming schema (do to LastPass) when I then tried to cleanup the collection nested for example:

Collections / names:
shared-Customers/Customer A/Administrators
shared-Customers/Customer A/Users
shared-Customers/Customer A/Services
shared-Customers/Customer B/Administrators
shared-Customers/Customer B/Users
shared-Customers/Customer B/Services
...

Now I removed the parent collection "shared-Customers" in the hope that all would just go out and be root collection, like so:

Collections / names:
Customer A/Administrators
Customer A/Users
Customer A/Services
Customer B/Administrators
Customer B/Users
Customer B/Services
...

But instead they kept their old "Nest collection under" now just as "shared-Customers (deleted)" and still looks like they did.. now just without any parent.

In general I see that if I manually edit all it's child collections do not follow, but need to also be manually be edited - is this a bug or suppose to be like this that it's not a foreign-key/link used in "Nest-collection-under"???

Collections / names:
Customer A/Administrators
shared-Customers/Customer A/Administrators
shared-Customers/Customer A/Users
shared-Customers/Customer A/Services

It do anyone know about a way to do this in some way or some sort of command/script that will do this for many at a time as I have around +100 collection with additional +4 child collections

Thanks.
