Why I can't see tags's icons ?

Hello, despite I've set icons for many tags, I don't see them, can you help me ?

brian85 Can you also share one of tags modal window in admin area?

Oh ok sorry I've found my mistake fas fa-bolt was not a default value ! My bad ! Thank you !

Use "fas fa-users-cog"
instead of <i class="fas fa-users-cog"></i>.

Adjust color starting with "#"

Thank you for the tip !
