Range extended issues

Hi, im experiencing some issue with my aeotec 7extenders. My zwave buttons do not respond most of the time so i placed a extender between the buttons and the homey. Connection with the extender is perfect. But nothing is connecting to the extenders. You guys have any idea why this buttons dont take the extender as the way to go. Tried to heal many times but no effect.

Hope someone can help me solve this
