Bundle version too low

[Arjay7891]

Hi,
I'm trying to follow the tutorial to set up a simple cluster, but after following all the steps there is an error in the "Problems" tab saying
"The bundle version (3.0.0/3.0.0) is too low, must be at least 3.0.1"

When I try to run OSGi anyways I get:
Status ERROR: bndtools.core code=0 Error initialising bnd launcher java.lang.IllegalArgumentException: Default handler for Launcher-Plugin not found in biz.aQute.launcher

could you let me know how I can fix this issue please?
thanks,
Roman
