This is resolved in 7.96, patch 13, planned for release in Blackbaud Hosting Services in fall 2018.
In the meantime, pledges encountering this issue can be posted in one of two ways:- On the General tab of Post to GL, select to Post the transactions in Summary, rather than Detail. Note, this will post the total sum of all the installations to each account. Due to certain installations posting as negative, they may need to be corrected in the General Ledger batch after posting.
- Manually enter the journal entry in FE (How to add a manual Journal Entry batch in General Ledger 7). To help enter the data, take a screen shot of the gift's GL Distribution or right-click in the GL Distribution grid and select Export GL Distribution Grid to Excel.
