A friend of mine that is  FA expert (Patricio) solved it!! just unchecking the "Location Notifications" at the System and General GL Setup page. It works fine now.

Hi to all. I have the same issue, but a little odd. I've instaled 2.4.8 from scratch, and did one negative adjustment and everything in the GL went well. The second adjustment (negative/egress) was booked as positive, and also positive income in the item movement. I dont know what to do.
