Filled out radio buttons show tiny cross

In a certain PDF, when we fill out radio buttons and generate the filled-out PDF, the selected radio buttons show only a tiny cross (see image). The check boxes on the other hand show a normal cross (see image). The original PDF however, when filled out manually, shows normal sized radio buttons. We also know about other software approaches that do not corrupt the size.


This behavior makes our desired process impossible. How does it happen like this? Can we prevent it?

We fill out the radio buttons as documented. We have already tried numerous settings and setting numerous properties, but we started with the very simple code as follows. We do not change any of the document or field properties.

Aspose.Pdf.Facades.Form.FillField(radioButton_fullName, “2”);
