Save file name not the same as load file name

Hi! I've noticed that when ecogVis saves the nwb file automatically for the first time, it does so with name structure subj_subj_block.nwb and then, it tries to load that same file assuming the fname is subj_block.nwb. I've been needing to quit the gui, manually rename the file and then open the nwb file again. 

Am I doing something wrong or is this a bug?

Thanks!
