Element parse errors on deployed project

I am seeing element parsing errors when I view my deployed project via the apigee web gui. See below for example:

Seeing deployments in this state does not instill much confidence in whether this flow is working or not or even what state this project is in after deployment. How do I rectify this?

The example above was a copy and paste of the screen showing the error. I didn’t see any warnings saying this will be removed from the post, however the XML looks like:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> configuration <#text>identity <#text>-

</#text><#text>v1undefinedundefined</#text><#text>-undefinedundefined</#text><#text>environmentundefinedundefined</#text><#text>-undefinedundefined</#text><#text>configundefinedundefined</#text>undefinedundefinedundefinedundefinedflow.ee.configuration.jsonundefinedundefined

I have no idea where the #text tags are coming from – definitely not in the source.

This error only happens in Internet Explorer – Firefox and Chrome appear ok.
