Mobudget Pro App purchased with paypal still showing as trial in windowsphone store

[WPCentral Question]

Hi, today i purchased Mobudget Pro app through Paypal. Inside the app settings, there was option to pay using marketplace and using paypal. I went ahead and purchased using Paypal. Now the app is fully functional and all the features are available. But when i check in windows store it is still showing buy option. In the purchase history in the windowsphone store site, it is showing up as trial. why the status hasnt been updated yet? Also if i uninstall and reinstall the app will i have to pay again?
