games not showing in my recent played games list

[Dipen]

I have 42 iso files on my android. i am using PPSSPP ver 1.7.5 from play store, recently updated. In the "recently" played list it is showing only 30 games. Rest of them i have to manually go to the folder and play. once played that game thumbnail would show and the last thumbnail in the list would disappear (from the recents list, the iso is still in the folder). Is there a limitation to the number of games shown in the recent screen?
