A few bugs I'm noticing with GCC 1.0.9.4 (windows 10)

1. Under administrator I can remove devices I don't have to try to clean it up. However these changes are not saved and there is no dialog box to save changes. When I restart all the options are still there and the opening start window returns. In addition, if I "clean up" the icons in the bottom, these changes are not saved upon the restart.
2. I'm getting consistent crashes when I navigate to the "Backup and Restore" menu. It tries to open it and then the program crashes pretty much every time.
3. Having problems with the Measurement Data. I clicked "read and save" and it logged data and displayed it. When I went back to it, I pointed it to the same .txt file that was used before to save to, chose "append" and got an error that it was in an incompatible format. Therefore I am only able to graph the new data - it will not graph the old data. After a "read and save" I'm not able to point the data viewer at the old file.
