Single product page tab name change

Hi!

Last year I managed to change the Description tab to “Prosjekter”, which was more appropriate to the use at the time (and my site is in Norwegian). Now I want to change it to something else but I can’t for the life of me remember or find out how I did this.

I looked for snippets I might have added to functions.php, the only one I have reorders the tabs, not rename them.
I thought I might’ve used a translation plugin, but can’t find it in the translation files either.

Does someone here have an idea or suggestion how I managed to do this? Where else should I look?

Thanks in advance for the help!
