Mp3 Player Related Problems?

I am using Twinmos Mp3 Player - Red Rock S11 MP3 Player:

My problem is since Mp3Tag v2.34a, when playing the song - it's title is cutted off one character from behind.

For example..

Kenapa --> Kenap
We Belong Together --> We Belong Togethe
King Of Wishful Thinking --> King Of Wishful Thinking
Ocean Deep --> Ocean Dee
Abracadabra --> Abracadabr

and so on..

Before this, all mp3s tagged with Mp3Tag were fine enough, no problem like this.

I found that it is also bug in v2.35.

So, any explanation for this? Thanks a lot.

p/s: For info, my mp3 player is only displaying the song title.
