Next Challenge will not save on dynamic challenge

We have updated our on-premise (self-hosted) CTF server to 3.6.0. We have added several challenges using the dynamic challenge type on all the new challenges added. In addition, we have been attempting to use the Next capability for the new challenges just like we had done for the already existing standard type challenges. When we make the selection of the next challenge and click on Save, the system blanks out the Next Challenge field. If I make an entry in the Next Challenge field and click Update, it appears the Next Challenge data is saved. However when I exit that challenge and the come back to it and review the Next information, the Next Challenge field is blank.
