How to use a Filter to create your Plan - inconsistent results

[Debbie Weinstein]

Help! 

I am trying to build a plan in Portfolio based on a Jira filter.  When I use the Filter in Jira I see a certain number of jiras.  When i create my plan using the same filter I see much fewer jiras being brought in.  I select Story Points and All Releases.  All issues have Story Points and Fixed Version set.

Are there other things that come into play? 

(apologies for the multiple posts. accidentally put this in the wrong board.)
