Increasing Distribution amount to fully funded line

While creating P10 of ABCDCD-14-F-00140, which already had 3 lines of accounting (2 lines for CLIN 0001 and 1 for CLIN 0002), upon validation of the award after adding Distribution 3 to CLIN 0001 and Distribution 2 to CLIN 0002, I received an error indicating that the encumbrance date for Distribution 1 of CLIN 0002 was not within an open GL period.

While adding funding to CLIN 0002, the first thing I did was to increase CLIN 0002s pricing data. However, based on how CLM works, if your existing LOA is fully funding that line item, CLM automatically adds funds to that line item to keep it fully funded. In this award, when I increased CLIN 0002 from 74409.6 to 88361.4, it automatically increased the CLIN 0002 Distribution 1 to 88361.4 as well. In order to add another distribution, I had to correct the distribution back down to the original value.
