BPMN 2.0 intermediateCatchEvent is interpreted as a Task when importing in Bonita Studio 6.4.2.

Hi,
I have a diagram that contains a signal catch event in a BPMN 2.0 xml file (intermediateCatchEvent tag).
When I import this diagram through the BPMN 2.0 import in Bonita Studio 6.4.2, the signal catch event is interpreted as a Task.
Even, if the BPMN file is generated with Bonita (export as BPMN).
Is it a limitation in the BMPN import fonctionality ?

I would create a Bug report for this https://bonita.atlassian.net
