Where Do I Change The Text Value Of Tabs For The Tags Addon?

Hi, so I when you go to products.update there are tabs like 'SEO', 'Variations, etc. for addons that apply to products right? Well, I changed the title text in the 'Tags' tab temporarily but I forgot to document how I did it and now that I want to change it back I can't seem to remember where I changed the text. Any ideas on where it is?

Administration -> Languages -> Translations

It should be there

Ah no, I didn't change the content of the language variable that had 'tag' as the value.But I was able to find what I was looking for, I changed the 'title' in the products.post.php in the backend tags controller folder.
