Linking xfers between accounts falis to join correctly

OS: Windows 10
HomeBank Version: 5.5.7 (portable)
GTK: 3.24.33

When linking two transactions between accounts as an xfer, older versions used to change the category and info automatically to transfer and "link" the transactions. 5.5.7 appears to find the transactions in respective accounts, but doesn't show link/category change/etc.

Steps to reproduce:
- Create a new database
- Create an account, set the name to "Checking", set the type to "Checking"
- Create an account, set the name to "Savings", set the type to "Savings"
- Go to "Savings" account and add a transaction:
  * Set to "Income"
  * Set amount to 100
  * Click OK
- Go to "Checking" account and add a transaction:
  * Set to "Expense"
  * Set amount to 100
  * Click OK
- Save database
- Open "Checking" and double click on the 1 transaction
- Change type to "Transfer"
- Select "Account To" as "Savings"
- Click "OK"
- Observe dialog has 100% match on savings record
- Select transaction from "Select action for target creation"
- Click "Use Selection"
- Observe transaction in list is still listed as "Expense"

This observation came up because I had imported my checking and savings data from my bank, and have a regularly scheduled transfer. On updating the checking to savings transfer records, it didn't update correctly. Earlier versions successfully changed.
