Text disappears when I render

[Taizan5F9C]

Hello everyone,

I’m new to adobe premiere pro. While I was text editing I encountered an issue. The text shows when I edit it but some parts of the text disappears when I render. Could someone please tell me how to fix it?

Not sure what's going on here. What are the "Source Text" keyframes for?

To add "writting effect" to the text. I saw it on a Youtube tutorial. By adding keyframes letters appear one after another.

Delete preview files and render again.

Thanks. I tried but it didn’t work. I reduced the "scale" to 41.0 and rendered it. And now I can see the whole text. But if I make it bigger than 41.0, some text parts disappear.after reducing scale
