Hello,

I saw the screenshots you attached.

Unfortunately, you cannot replace the titles of the pages you mentioned with your categories.

Therefore to change the text in those areas you need to follow the instructions below:

1) For the 1st screenshot you can simply edit the page and rename it to change the title.

2) And to edit change the titles you mentioned in your second screenshot you need to install and use the loco translate plugin.

You can watch the video in our detailed documentation in the following link:

If you are trying to ask anything else the provide with some relevant screenshots of the specific area-after with some more explanation to check it myself and help you out accordingly.

Best Regards.
