I had this same issue, and was able to resolve it using the suggestion above by Nitin Verma. If you have an open bank rec with items already matched, you'll need to add the Bank Statement No. and Bank Statement Line No.'s to the Check Ledger Entry table. Create a Config Package of table 272 - Check Ledger Entry. I only included the following fields - and be sure to turn Validate Field to OFF for Statement No. and Line No. or they won't update:

After exporting the Config Package data to Excel, I opened up the Bank Reconciliation Page in BC and used Page Inspection to click on the imported bank lines to find the Statement Number and the Statement Line Numbers of the check ledger entries that are matched in the statement. I then added these numbers to the config package data in Excel. For example, clicking on the bank line of a particular check, I can see that the Line No is 10000, so I add that to the corresponding line for that check in the Check Ledger Entry data, and I also add the Statement No. BANKREC000001:

Once the Config Package was uploaded and applied, the issue was resolved. There was a few where I typed the wrong Line No - you will get an error and BC will tell you what the line number should be.
