edgemicro cannot synchronise settings when starting

My local edgemicro does not seem to be able to download latest configuration. I think so because I deleted some endpoints and created new ones, but edgemicro still can see those deleted but cannot see newly created. Then if I try to re-start edgemicro, it reports "404 Not Found" on /products endpoint:

$ edgemicro start -o it-xxxxxxxx-eval -e test -k xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx -s xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

current nodejs version is v8.11.2
current edgemicro version is 2.5.16
