CHIRP

I have an Icom IC-E92D and am seeing some strange behavior with CHiRP. Auto detect for download fails, but manually setting the model then correctly downloads all of the memory locations. When using RepeaterBook import the offset column in the CHiRP radio memory display is completely blank, but if I export the data to a .csv then the offset column in that file is correctly populated. If I manually try to enter an offset value for a memory location in CHiRP then it reverts to empty and does not update the radio. This is the first time I have tried to use CHiRP with this handset so I am unable to say if it worked with an earlier version of the software or not. I have a attached a screen shot of the CHIRP screen that shows the offset column blank, and the .csv file showing that the values are there. Another interesting oddity is that the software will not export the DSTAR memories to the .csv as it say the radio does not support it, even though those values are valid in the memories...
