Open advanced settings in populate and apply the below changes:
1. If field isn't empty - Change from default value to "Replace text"
2. Populate text using physical keystrokes -
Try with Enable this toggle button
If not working again then disable it and try.

After tried the above approach, If you still facing any issues, allow your PAD to open notepad to type the text, then ctrl+A, ctrl+C, ALT+F4, and then after open your web page allow PAD to send the keys ctrl+V.
