Когда я говорю «Очистить» на экране транзакции (чтобы очистить значения или имена, которые я ввел для даты входа, кода подразделения и т. д.), он не очищает «код подразделения, номер клиента и первый номер кода группы». Я тоже не могу удалить его вручную. можешь это исправить, пожалуйста. Другие работают нормально (например, дата входа, имя клиента, валюта, тип…). Я не могу удалить, когда создаю нового клиента. Допустим, код устройства – 25567. Если я удалю вручную в порядке "5,2,5,7", тогда останется только число 6, и я не смогу удалить 6.
