The problem here is that the user is filtering their view by a shortcode parameter, however when a shortcode is passed into the view parameter the formatting breaks.
Solution:
In order for you to do a shortcode in shortcode type setup you will need to first ensure that you're creating a content template with our Toolset plugin. The nested shortcode setup will only work with Toolset.
This is because wordpress core dropped support for using shortcodes as attributes.
A few other plugins have added support for this but if you're creating a page through wordpress core then it won't work.
The problem here is that the user wanted to export their views.
Solution:
Unfortunately it would appear that views doesn't allow you to export its components directly but you can still do an export using the module manager plugin.
The module manager plugin can be used by going to Toolset -> Modules.
From there you will be presented with all the components that were created in Toolset. This includes Views, Content Template, Post Types etc.
On the right hand corner you will see the option to create a new module. Create your new module then drag and drop the components that you want to be in this module then save and export it.
To import you will go to Toolset -> Import/Export and under modules you can use this to import the modules that you've just exported.
Finally the module manager can be downloaded from the link below.
