Hope it helps.

Can you share some details on how the bank account was set up (e.g., in Chart of Accounts)? Firstly, the related accounts for payables/receivables may need to be tagged for "Allow Reconciliation." Typically, Odoo will enable intelligent logic to suggest matching transactions from Invoices or Vendor Bills (for example) to bank transactions.

Secondly, you can add more of those gray reconciliation buttons you see when in bank matching mode (if you need to add more from the default) by going to the Reconciliation Model menu... Odoo documentation is not updated for latest v18.4e the last time I checked, and you can go to that via any bank/cash Dasbhoard card's "three-dot" menu, and select "Models" under Reconciliation:

There you'll see the pre-defined options (the gray buttons you'll see when in Bank Matching mode), and you can add more for your use. Create new ones sparingly, as it might confuse a user too much, and default ones are already enough.

NOTE: You may need to also set up "Outstanding Payments" and "Outstanding Receipts" accounts for your bank accounts for better tracking and bookkeeping, as needed. They're first created in the Chart of Accounts, then configured in the specific bank journal's "Incoming Payments" and "Outgoing Payments" tabs. See Odoo documentation: https://www.odoo.com/documentation/saas-18.4/applications/finance/accounting/bank.html#outstanding-accounts

Hope this helps.
