Trailing spaces in step template names permanently break the Export feature

If you accidentally have a trailing space in a template step that you add, it will appear to work fine within the OD site, but the “Export data” feature breaks with

Hi Chris, sorry for the slow response.

I have managed to reproduce the issue and have created a github isse which you can use to track the progress.

We apologize for any inconvenience this may have caused.
