Problem with 2 property keys (conflict with property keys ?)

ALEX SEYMOUR <alex....@...>

Hi everyone,

I have a problem with 2 property keys, named:
"ex_value" String

I don't know why, on every vertices I created,  ex_value property name is  replaced by feed_name.

>g.addV("test").property("name", "example").property("ex_value", "test1")
=>[id:3686404256,label:test_example, name:[test1], feed_name:[test1]]

feed_name property appear in result, but I didn't used this property, I used ex_value

the result is wrong

there is 2 feed_name properties, ex_value doesn't appear

I don't know how I can resolve this problem.
