I have contacted the Company secretary on the name change, and it may be a technical issue on the trading platform algo's.
Will contact CMC markets, and ask the question.

I am not sure why this is. It seems that when a company is suspended and or re-instated it appears on this platform showing a name change.
ATM was suspended on the 3rd and re-instated on the 10th.
There is no plan to change to HDY’s name. I suspect this is an technical issue with the platform you are using.
