cannot find full text from Wiley

Endnote cannot find full texts from Wiley, only DOI are found. Is it normal?

 (I make sure that my institution have subscribed those electronic journal issues and I have done the eproxy url setting in EndNote preferences)

For example, the journal " Clinical oral implants research" v.25 no.1 whichis free copy, so  I can find full text of this journal issue via EndNote, however, " Clinical oral implants research" v.25 no.2 which need subscription (my institution has subscribe it) that I cannot find full text, only DOI is found.

So, it is normal situation?

If not, is it EndNote problem? or Wiley problem?
