I'm having the same problem. Did you solve it?

I'm having the same problem, I think this problem is related with the plugin.

Nice finding! This was not covered into our testcases and indeed this is happening with the SDK itself.

On this PR we can see the issue happening, it is something with the way PHP encodes content while saveXML() is called.
