Loco Translator not working

Hi guys,
I am trying to force woocommerce to change the text in dropdown filter boxes shown on shop page.

Currently, the various options read as follows

Show 50 Products
Show 100 Products
Show 150 Products

I want to change the word “Products” to “Items”

I go to Plugins>Woccomerce/woocommerce.pot
Select “Editor” tab

There isnt available source text for “Show 50 Products”, “Show 100 Products” etc

I have tried just using Products on its own, however that doesnt seem to work

I have tried to do this in the translator, but woocommerce is ignoring my translation.

Can someone provide a step by step walk through on exactly how i can get this to work?
