I've customised an admin theme using the minimalist_blue theme as a base. I've near enough got it completed but There is text appearing above submit buttons which I can't seem to get rid of. I would also like to change the colour of the text and background hover from blue to either Green or Brown but can't find where this found. I have circled the text on the attached image. I'm using ProcessWire v2.4.0 if this makes a difference. Thanks in advance for any help.
