Tab Products > How to Change Theme Typo "On Sales" to "On Sale"

Okay, I've been searching the forum for this question - as I am certain that it has been asked before - and the only answer that I've found is unacceptable. There is a Typo within the Theme's Visual Composer's Tab Products. "On Sales" is very bad grammar and it should be "On Sale".

I need to quickly update this information on my site as it appears to potential customers that we are idiots.

I've been looking through all theme files to find where this 5 letter word is being pulled, but have not yet located the source so that I can correct this Type. In previous forum posts I see that "you can't change this, but you can translate it". No an option. We are using the English (United States) text option already.

I've also seen posted that this cannot be corrected. Also not an option.
This text is being pulled from somewhere within the theme files. Please provide me with the path to that file so that we can correct the typo within your theme.

I also highly recommend adding this bug to your long list of items to be patched in the next release of this theme (along with fixing the site load time!).

Your quick response to the file location would be greatly appreciated.
