I believe I can see the issue now. In the lite version you have both Posts and Pages enabled, while in the pro version is not.
It is because there is a minor difference in options, it has been just updated with the latest release of the pro version, the lite will be updated tomorrow:
– Lite version Posts and Pages: https://i.imgur.com/YeGXuQa.png (this is going to be changed)
– Pro version Posts and Pages: https://i.imgur.com/ZsJAmN7.png
I figured out that the result with the weird title you are seeing is a comment result, that is why the title looks incorrect (as comments don't have titles). It might have been enabled by accident. If you disable that as well, and enable posts and pages as results, it should display the same results as the lite version: https://i.imgur.com/o7IWIT9.png
Let me know!Best,
