Scroll bars not appearing

In Tap forms, scroll bars (both vertical and horizontal) are not appearing. To my knowledge, the issue isn’t occurring in any other app.

In my research to find the cause, did see that this can be because of compatibility issues with an application and Mavericks. I went to the apple system preferences and selected show scroll bars > always. However, the issue persists in Tap Forms.

The only other thing that I see to try is uninstalling Tap Forms and re-installing it. Not sure of best way to do this or if data will all be deleted.

Please let me know what you suggest about the scroll bars. Thanks!
