Native Keyboard issues

[NoDegree]

Hello I have been playing PES 2014 for PSP and recently updated to the newest version.

But I noticed a problem when I activated ''Use system native keyboard''


When I use the native keyboard, it doesn't seem to register the last letter.




But when I use the regular PSP keyboard it works just fine.




Is this a problem other people are having and is there a way for me to fix it?
Or do I have to wait for the next update?
