Data on screen not showing for the first time upon clicking the page

Hi I am having a problem where my app displays some data from an excel sheet. However, when the page shows for the first time, the data is not showed. After clicking the page once however, it seems like all the data will be loaded and accessible from all of the pages on my app. Does anyone know what is going on and how i may fix this problem?

Hi Louie,

I need more information, namely the oml, in order to help you.

Hi Joao, 

Thank you for the response. We have managed to find a solution. The get function for database entities does not work when we redirect from the splash screen to a screen. So we used the refresh get entity on the screen.
