There is no way to change it through the ACP, you need a theme or a plugin to override the breadcrumbs & page title. Maybe nodebb-plugin-customize can help.

It is public: https://community.tryb.cc/
Any help would be HUGELY appreciated. Thank you so much again @baris
Very strange... I switched back to Persona to see if it had anything to do with my recent switch to Lavender. All worked fine in Persona.
So out of curiosity I switched back to Lavender again - and it's all working fine!!
How very bizarre!
Thanks so much for your help.
I hope to be able to give something back to this group one day, as it's been such an amazing resource for me. You guys are all amazing. Thank you.
Just one other update on this, in case it's useful for other users...
It seems to be this plug-in that creates an issue on lavender: [nodebb-plugin-category-join-group]
-I had Persona theme - all fine
-I changed to Lavender - all fine
-I installed and then uninstalled above plug-in, and thought nothing of it.
-Problem arose with categories...
-Reverted back to Persona and all was fixed
-Once again reverted back to Lavender, and still everything was ok.
-Tried again to reinstall above plug-in - problem came back again
Again, I have flip-flopped between themes and the problem is sorted, but it definitely seems that the above plug-in doesnt agree with Lavender theme for some reason. Which is a shame, because I'd love to use this plug-in.
I hope this might be useful for others.
