Yes.  The difference between "Shuffle chess" and "FRC" is that Shuffle chess
does not allow castling, except when the kings and rooks are placed on the
usual places in the opening position.

Your games are definitely Shuffle chess, not FRC.  You can see this by
observing that no castling ever takes place in the games, and also by looking
at the FEN strings in your PGN files:

>>[FEN "[D]bbqnnrkr/pppppppp/8/8/8/8/PPPPPPPP/BBQNNRKR w - -"]

The first token after the letter "w" encodes the castling rights.  When
this token consists of just the single character "-", it means that there
are no castling rights whatsoever in the initial position.  In an FRC
game, this "-" sign would have been replaced by "HFhf".

Unfortunately I cannot tell you what you are doing wrong.  The Shredder
GUI works fine for playing FRC, and the castling rights are correctly
encoded in the FEN strings when saving a game in PGN format.
