Quick Fix

module-swatches/Model/Plugin/EavAttribute.php

Instead of this:
if (empty($option[0])) { return false; }

Type this:
if($option[0] != '0'){ if (empty($option[0])) { return false; } }

@oroskodias Unfortunately, I could not reproduce the issue as you described it. Can you please let me know is this problem is relevant for latest Magento 2 release version?

[orozcodiaz]

@smoskaluk I see same code in 2.1.7. Issue is still there
