contribution adjustments/adding acknowledgements

Hello all,

We recently discovered an issue when making adjustments to an existing contribution. If we use the contribution editor to adjust a contribution and add a new acknowledgement (regardless of whether or not there already was one), the following happens:

1. we add the acknowledgement

2. when we check the contribution from within the constituent account, the unprinted acknowledgment appears on the acknowledgements tab

3. when we generate the acknowledgement, we get a blank report

4. when we return to the constituent account and view the contribution, the acknowledgement is GONE from the acknowledgements tab

This is the case across all different acknowledgements and campaigns. We did not have any issues with this before converting to v12, so I am not sure if it is a bug, or if we missed an important step in our conversion or what... but I'd love any input or advice!

Thanks,

Sheila
