Also csanchez, seems in your example you disable Dynamic Text Layer option and scale text layer frame a lot. I might be wrong, but layer handle extends too far from letters even compare to default unusual PhotoLine-style extending.
In PhotoLine by default when you move Text layer handle, text size remains unchanged, but only frame transforms (this is sort of publishing-style behave). This switches text layer from Dynamic to Static Text Layer mode. Layer frame size no more followed to text size.
You can always switch back to Dynamic Text Layer in last tab of text tool settings.
This default behave is rather unusual for image editors, but rather usual for publishing apps. PhotoLine is multipurpose tool. There where few discussions about this default text layer behave and most users vote for publishing-style default behave for text layer.
To keep Dynamic Text Layer during transform you can hold Command on macOS or Control key on Windows and drag layer handles (Command+Shift will keep proportions).
Or you can just add Text layer to Group and transform Group instead of actual text layer. In this case you don't need to hold Command key every time because Group layer with text inside will behave exact same as any image or vector layer.
