Attach to manual invoice line

Content

We have generated an invoice, which is created with 3 lines, each for an event. It is in Draft status.

e.g. Line 1 for Event 1 100$, Line 2 for Event 2 110$ and Line 3 for Event 3 120$. Invoice amount is 330$.

Now, We have deleted all three lines and created a manual line Line 1.

Then, under Invoice distributions section > Eligible Billing Transactions tab > Events, we selected the 3 Events and clicked on Attach to Manual Invoice line, provide the Manual invoice line and click Submit.

The events are not linked to the manual invoice line. Nothing happens. (Also, there are multiple lines showing for the events with the exact same details under Invoice distributions section > Eligible Billing Transactions tab > Events).
