I went ahead and exported the Layouts from here:

I then re-imported them.
I checked:
Overwrite any layout if it already exists
Delete any existing layouts that are not in the import
Overwrite layout assignments
Before I pressed "Import", I checked "Show log" as well.
There is immediately after a JS error in the console:
Failed to load resource: the server responded with a status of 400 (Bad Request)
The bad request happens on /wp-admin/admin-ajax.php
Means, your server likely disables AJAX or something makes it impossible to call/use it.
Locally, this import works just fine.

Now, I thought it should be due to either the server, but it's not.
On a local duplicate of your site the same error happened.
As soon though I disabled all non-Toolset Plugins (I kept WooCoomerce our it's Toolset AddOns for it), the issue is resolved.
I figured that it is the plugin "Sublanguage" provoking this.
I was able to replicate this issue on another install using the same plugin and the same import files.
I need to check if this is as well replicable with any import file or due to the specific import file, although I think it is an issue that is due to a conflict (general) between that Plugin and any plugin that uses the admin-ajax
We have a team of developers that as well looks into compatibility issues, and we usually follow this steps:
- we try to replicate the issue "clean"
- figure out on what end of the plugin the issue is sourced (our, their)
- we then either contact the authors or fix it ourselves, depending on above.
For this purpose, I escalated the ticket to the compatibility team.
I will keep you in the loop of progress here.
For now, just disable that plugin while you import, it should help.
Related to the Toolset Starter theme, I would suggest trying switch to a Theme that you can maintain.
Toolset Starter is quite minimal but not as minimal as it is possible (and the more minimal, the less maintenance you need).
A while ago I created this boilerplate that does the same as Toolset Starter but much less "fancy" (it is really just a "plain white slate" where you can apply Layouts/Views designs from one edge to another of the website)
It's not a Toolset product so we don't support it but you are free to use it and build on top if you like to:

The code is commented extensively so to allow understanding what is going on, by just reading the comments in it.
It can allow you to understand the logic behind it and go further with your own ideas.
It may be a solution for the future, having your own custom theme with minimal maintenance requirements (and a truly tiny size...).
Thanks for your patience!
