If the sample picker is only showing durations and not sample names please follow the following procedure
cmd/ctrl click on the 'i' at the bottom right of the interface. This will re-initialise the instrument and will take a bit of time. The number of voices will go up and the ram will also rise significantly. Once the number of voices playing gets to zero again, you should have the names back in the picker, and if you select a sample it will return the ram footprint back to normal
