Jpa facet show 2 datasources

Hi, I have a problem using small window using spring jpa persistence. Shows two datasources when in fact I have one.
I am using xml configuration for the context and persistence.
It's a maven project with web ,spring and jpa facet enabled. Attached image
There's something wrong in my settings?
