What does the red triangle/warning symbol mean in Zik?

When looking at products and results in Zik, some show next to them a Red Triangle. This is an indicator to look closely at the item before listing it.
Possible causes can be: multi-pack (so make sure to list same quantity), Vero warning (see here: https://support.umbrellaus.com/portal/kb/articles/where-can-i-find-the-vero-list-an-item-thats-not-on-the-list-was-removed-for-vero-why), or other reason for concern. This will only appear if you use the (free) Zik browser extension.
