无法使用掩码和验证器删除 QlineEdit 中的文本

我写了一个手机QRegExp验证器，将其添加到LineEdit中。另外，我还加了一个面具。（经过几次错误后，我意识到必须在验证器之后添加掩码，否则什么都不适合）验证器（QRegExp）：

QRegularExpression numberRegex ("^\\+\\d{1,1}\\(\\d{1,3}\\)\\d{1,3}\\-\\d{1,2}\\-\\d{1,2}$");
QRegularExpressionValidator *numberValidator = new QRegularExpressionValidator (numberRegex);

为 QLineEdit 添加掩码和验证器本身的代码：

ui->lineEdit_4->setValidator(numberValidator);
ui->lineEdit_4->setInputMask("+7(000)000-00-000");

一切正常，数字以正确的形式输入，但是有一个问题：写数字时，我可以通过按（退格）擦除，但是输入最后一个字符后，我无法再擦除了。

UPD：如果我制作一个末尾带有附加“0”的蒙版，那么所有内容都会被删除，但它不再适合我需要的蒙版。 TOTAL：如果掩码和验证器“重合”，则在写入结束时无法擦除 UPD2：如果我单击 ALT+Shift 最后 2 个符号无论如何都会被删除

原文

I wrote a mobile phone QRegExp validator, added it to LineEdit. In addition, I added a mask. (After several mistakes, I realized that the mask must be added after the validator, otherwise nothing fits) Validator (QRegExp):

QRegularExpression numberRegex ("^\\+\\d{1,1}\\(\\d{1,3}\\)\\d{1,3}\\-\\d{1,2}\\-\\d{1,2}quot;);
QRegularExpressionValidator *numberValidator = new QRegularExpressionValidator (numberRegex);

code for adding a mask and the validator itself for QLineEdit:

ui->lineEdit_4->setValidator(numberValidator);
ui->lineEdit_4->setInputMask("+7(000)000-00-000");

Everything works correctly, the number is entered in the correct form, but there is a problem: When writing a number, I can erase by pressing (backspace), but after I enter the last character, I can't erase anymore.

UPD:If I make a mask with an additional "0" at the end, then everything is erased, but it no longer fits the mask I need. TOTAL: if the mask and the validator "coincide", then at the end of writing it is impossible to erase
UPD2: if i click ALT+Shift last 2 symbols will be erased anyway
