Overlaying Text not showing in video in export

[Kolorado]

I could still reproduce this bug in 2020 with version 8.99.

For me simply adding an emtpy text clip somewhere in the project (in another video track) helped. No need to shift the existing text clips.

You tacked on your comment to a six-year old thread.  The overlay issue that you experienced may be due to a different cause entirely.

Overlays not displaying in export may result from editing errors or, especially with complex projects, memory limitations.  How a project is built is key.

Please be specific on what you see and did.  Better still, take a minute to share a project that has the issue so others can attempt to track it down.

The process is easy, quick and can be private.  Just follow these steps...

•     Back up --- With your project on the timeline, click on MENU at the top-left.  Click FILE|BACK UP PROJECT FILES TO FOLDER.  Choose a folder and SELECT FOLDER.
•     Upload ---  Upload the saved, numbered FOLDER.  Use a free server - Google Drive, MS OneDrive, etc.*  Do NOT upload the individual VPJ or export file. 
•     Get link --- Get a public link.  If using Google Drive click GET SHAREABLE LINK. Change "restricted" to "anyone with the link can view"  Click COPY LINK | DONE.
•     Share ---    Paste that link here, or click the folder at the top-right of this forum to message it privately to me.  It won't be shared.

          *    Before uploading, right-click the folder, click PROPERTIES.  Look at the File Size to confirm that it's not too big for the free space on the server.

I ran into a similar issue a few times (with different versions)

I recommend deleting all the cached files and restarting the computer before doing a final export. This seemed to fix the issue for me. And now, as a precaution, I do this almost every time before exporting.
