I tried to search for an existing issue in 8.2 version related to "ReloadSection" activity. It is an activity which is used widely. If ReloadSection is having the issue, we would have received some tickets related to it.
It is possible you are running into some Page context issue and might not be a simple reload section issue. I suggest that you verify from the clipboard that the data on the clipboard page for the section in question is correct. Also, please verify from the Tracer the parameters passed to ReloadSection activity to debug further.
If you are refreshing the current section, look for the parameter StreamName.
For refresh other section, look for the parameter StreamList and see if there are multiple tokens of same section name are passed, this can be critical here when you debug.
we are using refresh other section in the dropdown property action.
when i trace found two things 1. Reload section called twice 2. In First refresh it has correct StreamList, what is configured in refresh other section and In the second refresh it refers some other section in StreamList so it loads incorrect section in the screen.
one common thing between first refresh and second refresh section are referring same set of properties.
