QComboBox Does Not Display Current Text in UI When a Non-Default Value is Selected in a Qt for UWP Application

In the QComboBox, when I select a different value from the drop-down list, the selected value is not displayed once the drop-down list closes. The box still shows the default value (text). But when I observe the value received by currentIndex, it corresponds to the selected value. Whenever I select a non-default value, the UI seems to be blocked. I cannot interact with any other UI elements except the QComboBox element.

Whenever I click on the *QComboBox *and select a value, I do not get control of the UI back. Everything in the UI is stuck but whichever button I click is emitting the signal in the background. The UI does not respond at all.

ADDITIONAL INFO (Might Help in Your Debug Process):

I was tinkering around trying to understand what was causing this behavior. During this process, I stumbled upon a workaround to get the UI to respond again. If I launch a QMessageBox within the QComboBox's currentTextChanged signal, I get the UI control back (the currentText UI value changes to the value that I previously selected) when I press OK on the QMessageBox pop-up.
