Unfortunately, I have no really good idea, but one thing you should try is to re-install the applications and see if this fixes the problem. Otherwise, copy the files on a freshly formatted card, or even try another card. If this works, CALC's author might be interested in a problem report including a image of the SD card.
In my experience, most embedded and many desktop FAT file system implementations are buggy or incomplete, and it is quite likely, that this also holds true for the FAT implementation in the HP 50g (although I haven't analyzed the 50g's implementation in detail). I don't know, if this holds true for the 50g, but many files in the root directory in a FAT12 or FAT16 volume (in particular if they carry LFNs as well) or more than one cluster full of entries in a FAT32 volume are a common problem for incomplete implementations, so it is worth trying if avoiding these conditions would work around the problem for you.
