Kibana hashboards empty

Hello there,

I set up another ELK (E and K on one node, L on another) and a linux server with filebeat and metricbeat on.
I can see the log events from filebeat and metricbeats streaming to Kibana/Discover. I dropped the original indexes as they didn't work for the dashboard, and then
I followed the steps to set up filebeat and metricbeat dashboards and set up the index templates for both as well, all went fine.
curl -X GET http://:9200/_cat/indices returned a lot of indexes all are open.But when check on the filebeat system pverview dashbord and other filebeat dashboards. I got:

" Could not locate that index-pattern (id: filebeat-*), click here to re-create it"

This is not link for me to click...

I know someone hit the same or similar issues before. but I didn't see a clear solution...
Our ELK and BEATs are all on v6.3.2. Could you please help me with this?

Thanks a lot

Li
