KanBan Replenish / Setup Multiple Replenishment Bins

Hello,

We have been using KanBan Auto Replenish for a few weeks now & have several part numbers that are stored in multiple bins & have been able to successfully setup replenishment to multiple bins for the same part number.

For some reason, now when I go in to setup a second or a third bin for the same part number, the system tells me there is already a bin setup for this part & that the new bins setup is not allowed.

Has anyone run into this before? I am just wondering if maybe a setting had gotten changed within the last few weeks that does not allow for multiple bins to be setup for replenishment against one part.
