There is an issue with the import function or the save operation.
When importing a large amount of data, such as 10,000 records, screen operations like filtering work immediately after the import. However, the save operation does not reflect the changes.
In the case of a new import, if 10,000 records are imported, reopening the file results in the count returning to zero.
If the data volume is small, the save operation works as expected. Even if the first 1600 records import is successful, adding another 2600 records in the second import does not get reflected.
