Zephyr Scale Jenkins plugin keeps changing file path

Hi,

I am using the Zephyr Scale plugin with Jenkins. I'm publishing the results to Zephyr from a jUnit file generated by pytest. 

The plugin worked fine for a couple of days, but has now started changing the value in the 'File Path' textbox on the configuration screen to "target/surefire-reports/*.xml". 

The file I want to access is simply called "results.xml", but whenever I change it to this and save it, it remains at this value. Same thing if I remove the post build action and add it back

Does anyone know what my best course of action might be?

Thanks
