Unable to remove generator text and specific text using ultimate branding plugin

Hi,

I'm using Ultimate Branding plugin and I have two questions.
1. I'm trying to remove the generator text.
The generator text is still showing as "woocommerce" even though I set it to a different word. What should I do to remove it?
2. I also tried to change a few text using "Text Change" but some of the text inside the admin panel are still not changed. What would be the cause and how can I change them?

Thanks!
