Please find the sample data. In compact mode when we expanded using API expandAllData() it only expanded members (hierarchal) that were having content, now it expands everything. This never happened before. Please help.

Confirmed this problem in your JSFiddle examples as well. expandAllData is the problem, it's expanding blank hierarchies as well. Please help with this asap as this will spoil our reporting.
Hello Shripal,
Thank you for reporting the issue.
Our team will take a look at the described behavior and provide a fix with our minor release with the ETA December 22nd. We will notify you about the release.
As a temporary workaround, we recommend downgrading Flexmonster to version 2.9.107.
You are welcome to contact us if you have any further questions.
Kind regards,

Hello, Shripal!
Hope you are doing well.
Our team is happy to inform you that the expandAllData() method now does not drill down empty members in the multilevel hierarchy.
The fix is included into 2.9.118 version of Flexmonster: http://www.flexmonster.com/release-notes/version-2-9-118/.
You are welcome to update the component: https://www.flexmonster.com/doc/updating-to-the-latest-version/.
Please let us know if the fix works well for you.
Kind regards,
Solomiia
