Using the "Set array Elem" node to set the element of an array that is a structure (who's member is an array) that exists within an array will not set the element

A user has made an array of arrays by creating a structure that has a member that is an array. When trying to set a member of the array that is within the array, the "Set Array Elem" node does not work.

1. Open first person template
2. Create a new Structure
3. Add a member to the structure and make it an array (image for reference)
4. Add a few members to the array
5. Open the character blueprint
6. Create the blueprint in the attached image (set element to true)
7. Click play in Editor
8. Notice that the print string is reading out as false

Expected: The member would be set to true
Result: The member does not change
