Multiple cash deposits on sales order

We have a sales order that has currently 3 cash deposits unapplied to it. We pull from these deposits as lines ship. I’m wondering why, when we invoice, that only 1 of the deposits shows in the allocated cash deposit grid. I would think we should have the option to pick which of the deposits we’d like to take funds from. All 3 of the deposits have enough funds to meet the invoice need of $21,500.

Any help or explanation as to why the system behaves this way is appreciated.

These are the 3 deposits on the sales order:

This is the invoice allocation screen where we see only 1 deposit to select from. (We did not want to use this deposit but ultimately did because we couldn’t figure out another way)
