website Cannot import Solder modpack

[FHR]

Hi,
I hope this is the correct category for this issue.

So my problem is, I can't import a Solder modpack to the TechnicPack website.
I clicked "Create new modpack" -> "Import from Solder", I select my modpack from the list and it says

The modpack name you entered has a slug that already exists.

So I thought OK, someone has modpack with same slug. So I changed it to something unique, hit F5 on the TechnicPack page, but the same thing happened.

Then I tried to do it the normal way, thinking I would link Solder later. Well, I either get "The name has already been taken." or "The modpack name you entered has a slug that already exists.".
Which is weird, because I'm using quite a unique name and when I tried search to see if someone really has it, it showed 0 results.

After that I tried to put "http://api.technicpack.net/modpack/ytgamers" directly into TechnicLauncher and it complained about "Broken API Link".

Could someone help me with this please?

Hmm, looks like I sorted it out.

I created new modpack with totally different slug and THEN linked it with Solder.
