How do I change the way my name displays in messaging?

How do I change the way my name displays in messages? I use an alternate spelling professionally, and this is ehat appears on the booking platforms. I don't want to confuse guests by having a different name in messages. 

I've changed my profile settings, but that didn't help. Is there a fix for this without having to manually change the spelling on every message?

This would normally be set in your Theming area:
