After NPM warehouses aggregate multiple hosted warehouses, the tag of NPM is not normal

I create three rep：npm-nr-group（group）、npm-nr-001（hosted）、npm-nr-002（hosted）

npm-nr-group

I publish different versions of NPM packages in two hosted repositories：

1. version 1.0.16

npm --registry=http://xxxx/nexus/repository/npm-nr-001 publish --tag develop

1. version 1.0.17

npm --registry=http://xxxx/nexus/repository/npm-nr-002 publish --tag develop

When I successfully pushed, I checked the version from the group warehouse and found that:

npm --registry=http://xxxx/nexus/repository/npm-nr-group  dist-tag ls demo004

develop: 1.0.17

npm --registry=http://xxxx/nexus/repository/npm-nr-group  view demo004@develop

demo004@1.0.16 | Proprietary | deps: none | versions: 9

...
dist-tags:
develop: 1.0.16

npm --registry=http://xxxx/nexus/repository/npm-nr-group  i demo004@develop

+ demo004@1.0.16
updated 1 package in 0.316s

The result obtained by "npm dist-tag ls xxxx" is correct, but "npm view xxx" and "npm install xxxx" are wrong
