@theotherjimmy The proforma for this PR has been modified again! This will break our automation script once it goes live. Please do not remove the 'Description' or 'Pull request type' headers and please use a 'X' in the checkbox rather than a tick!
Also the description should summarise the change, not just say fixes #xxxxx
I have updated this for now to show how it should look.

@adbridge I did not remove the header. Directly from the comment in the pull request template:

Please tick only one of the following types. Do not tick more or change the layout.

I'm only following directions :P

This is yet another PR that's so simple, it can be described in the title, so the description element is superfluous.

@theotherjimmy I put the header back! It was missing both the '#Description' and the '#Pull request type' headers. So something or someone removed them on submission....

@0xc0170 Jimmy has a point about the semantics of the wording in the PR header wrt 'please tick one of the following'. Should probably say please add a 'x' to one of the following types to be specific....

Will fix

@adbridge I may have forgotten to add a space before them on submission, then the would have been stripped from the PR description.
