Swatch names and values can disappear with an uncorrectable error after "Saving" from another config tab

[Sanfam]

When an admin attempts to create a new visual swatch, they need to ensure that the "Admin" column has all of the necessary values entered. If the necessary data is absent, the user will be prompted to correct this discrepancy. If, however, they leave one or more admin fields absent while clicking "Save Attribute" from within another tab (for example, the "Storefront Properties" option set), they receive an error reading Admin is a required field in the each row and on navigating back to the "Properties" tab are shown a blank set of swatches with no ability to add, edit, or remove them. Any work put in up to this point is lost.

Steps to reproduce

1. Begin creating a new Visual Swatch attribute. Add several options, being sure to leave both Name fields on the top row blank.
2. 
3. Navigate to the "Storefront Properties" tab and make any changes
4. From the "Storefront Properties" tab, click the orange "Save Attribute" button.

Expected result

1. A (mostly) grammatically correct Error Message appears below the swatch list, Admin is a required field in the each row
2. 
3. The user is able to make their correction and add the missing required data

Actual result

1. User receives error, Admin is a required field in the each row at the top of the "Storefront Properties" page
2. 
3. The swatch list is completely absent with no way to add, edit, or remove data. This swatch needs to be recreated.

@nishantbkw , Please note that a ticket has been created internally, but will need to be prioritized by the Product owners before it can be worked on.
Thanks.

On a further note - if you get this error but all the labels are set, watch out for zeros. The check uses the PHP empty function which considers "0" to be empty (line 433 of vendor/magento/module-swatches/Model/Plugin/EavAttribute.php). Probably another bug.

I hope that this report help to fix.
The POST params with all attributes are right, but when Magento process the attributes, it breaks in the attribute number 199 (I tested in many attributes with this error), like the image below.

I think I just ran in to this with Enterprise 2.1.7 - any progress on this bug?
