Hello @JTimmer,
Step 1: Log in to the store's back office using the correct credentials.
Step 2: Go to "International" >> "Translations" from the left sidebar.
Step 3: Select "Front Office Translations" >> "{{your desired theme}}" >> "{{your desired language}}". You can refer to the screenshot here: https://app.screencast.com/svnUkbwKUdVSC. Then, click on the "Modify" button.
Step 4: Navigate to "Shop" >> "Theme" >> "Catalog" (https://app.screencast.com/DP2NTyY50cSWx). Find "Datasheet" from the manual pagination (https://app.screencast.com/CI39iFOqv2Amh) and update the translation. Click on the "Save" button to save the changes.
After completing these steps, refresh the front end to see the changes reflected.
