Bug Report: DCON Box

When doing any quests related to putting an item in a DCON Box, I can: > Collect the item > Take it to any DCON Box shown on the map > Open the DCON Box to see its inventory. HOWEVER: I cannot transfer the quest items and/or any other items into the box. There's simply no button promt for it. If I try to manually grab the quest item to drag and drop into the box, it won't let me place it in the DCON. This issue is preventing me from proceeding through multiple quest chains. Any solutions would be greatly appreciated. Thanks.
