Problem with Get Pages- Operator in combination with read csv (duplicate attribute)

I just started to use rapidminer and I have a problem with the operator "get pages". When I start my process, the tool says "Process failed. Duplicate attribute name: URL". I'm starting with a csv-file which has names in the first column. in the second column, which is called "URL" and classified as "file path" attribute in the first operator (read csv), there are links, which i want to open with the operator "get pages". in the "get pages" operator, I selected URL as link attribute. I hope you can help me... the whole error message is "Exception: java.lang.IllegalArgumentException
Message: Duplicate attribute name: URL Stack trace: com.rapidminer.example.SimpleAttributes.register(SimpleAttributes.java:124) com.rapidminer.example.SimpleAttributes.add(SimpleAttributes.java:203) com.rapidminer.example.AbstractAttributes.addRegular(AbstractAttributes.java:94) com.rapidminer.operator.web.features.construction.RetrievePagesOperator.doWork(RetrievePagesOperator.java:124) com.rapidminer.operator.Operator.execute(Operator.java:1002) com.rapidminer.operator.execution.SimpleUnitExecutor.execute(SimpleUnitExecutor.java:76) com.rapidminer.operator.ExecutionUnit$3.run(ExecutionUnit.java:811) com.rapidminer.operator.ExecutionUnit$3.run(ExecutionUnit.java:806) java.security.AccessController.doPrivileged(Native Method) com.rapidminer.operator.ExecutionUnit.execute(ExecutionUnit.java:806) com.rapidminer.operator.OperatorChain.doWork(OperatorChain.java:392) com.rapidminer.operator.Operator.execute(Operator.java:1002) com.rapidminer.Process.run(Process.java:1195) com.rapidminer.Process.run(Process.java:1091) com.rapidminer.Process.run(Process.java:1044) com.rapidminer.Process.run(Process.java:1039) com.rapidminer.Process.run(Process.java:1029) com.rapidminer.gui.ProcessThread.run(ProcessThread.java:65)

What happens if you change the name of the second column in the raw csv to something else, like "link"? Does the error still occur?
