BUG in GUI (Chess Tournament) or engine?

Who can help me to find what is wrong here?
I have outplayed a current grandmastergame between Stockfish 20180910 (32 Bit) and Komodo 10 (32 Bit) on my Android Tablet.
As GUI I used the App "Chess Tournament" by Javiolo from the Play Store.
As book I created a pgn File. Game started from move 29.
After 48 moves game finished to my surprise draw, with a Score +2.
Threefold repetition? No!

Here is the game in PGN:

[Result "1/2-1/2"]

[ECO "A48"]
