fresh recorded sample won't play in new program

well, after the trim section (where the new sample can be played using pads), the new sample can't be played in the new keygroup programm! other samples do so. when I select the a sample on the pads, I can hear all other samples on them chromatically. but the new recorded sound won't play, it just shows it's name. is this a bug or can I only use samples in the programs they have been in the recording process?

that has to be a bug. when I copy the sample, the copied (=equal sample with different name) sample plays in the program then.
