Background information:
Using Jira 7.6.3 with Portfolio for Jira 2.21.0 and we have the "new planning experience" turned on.
Problem statement:
Unrelated issues are being changed by Portfolio when I review changes and have the opportunity to commit them to Jira. If there is no direct parent-child relationship between an issue, it makes no sense to me that Portfolio changes data for that issue. See pictures below.
Plan details:
I've created a plan with the following issue type hierarchy:

The source issues for my Plan are:

My plan before clicking "Review Changes". Note how I have 3 epics with a handful of stories in each. 2 epics have the same parent Initiative and 1 epic has a different parent Initiative. Both of my Initiatives are tied to the same Product and this Product is tied to 1 Portfolio which is tied to 1 LoB as the hierarchy I've made dictates.

Picture of all the issues that Portfolio is trying to change that don't make sense to me. I've pointed out a few that should have nothing to do with this particular plan.
