Hi there,
does that notice from WP-SCSS show up also when using the parent theme or only on the child one? 

Hi, could you provide admin access so I can take a peek? Thanks ( please remember to mark the post as private)

Hi,

I'm trying to figure out why you see the category archives like that, as it should show up like this.

Did you edit/override any file or use any plugin that could possibly cause this?

That's odd, I'd need admin access so I can take a closer look.

Hi there, thanks.

When disabling all plugins category titles show as expected:

Please re-enable them one by one to detect who's responsible for filtering the category titles.
After that is sorted out if you still want to remove the 'Browsing Category'  text I can help you with some custom CSS without the need of using a child theme.

Hope it helps

Apologies about that although after 20 minutes trying to understand the cause of this I had to do it as disabling plugins is the first step to take when troubleshooting any issue. In fact turns out a plugin was the cause of it.

The official plugin to enable AMP support is AMP by Automattic, you might want to use this instead.

Please let me know if I can help any further.

Sure, you can remove the icon and the 'Browsing category' text by adding this in Customizer > Advanced > Custom CSS textarea

.archive .page-title span, 
.archive .page-title i {
    display:none;
}

Hope it helps

I got it, although my fix implies that you deactivate the plugin that causes the issue (AMP for WP), as the "Category: " text is not from Stoked! but from the plugin (considering that, even a child theme wouldn't help).

Okay I missed the fact you don't want to deactivate the plugin.

In that case what I'm saying is that even a child theme wouldn't help, as the plugin is overriding the theme filter with a higher priority, and would do the same with the child theme.

Out of curiosity, is there any specific reason you prefer the AMP for WP plugin over the AMP plugin by Automattic (Wordpress founders)?

Alright thanks for the info.

Wait though, I may found another solution as I've tested the plugin myself. 
I've set a higher priority for the theme filter, try by replacing the file in inc/fn/fn-tools.php with the attached one. It should revert back to Stoked! default archive headers design, then you can use the Custom CSS if you want to remove the extra stuff.

If it works I will include this in the next theme update so don't need to worry about losing changes.

Awesome! Glad that was finally sorted out
