On the first view, you have problem with Node71. I would suggest to remove it (remove unknown nodes) and pair it again - you also would need to manually repair your flows, eg. using script (ensure you note down the device ID prior removal) : [HOW-TO][Pro][Cloud] - Tool to FIX (advanced) flows after removing and re-adding devices
Also it’s not clear from your list,which of those devices are NON-battery, so they can act as routers. If you have lack of routers and higher distances from Homey, then issues may arise as Peter mentioned.
Als you can try to build ZWAVE map to see or to troubleshoot further.
