I am facing a strange problem. I have made assignment of a protein using sparky. When I open a project containing around 8 spectra and look at assignment table or resonance list, for most of the residues group has shifted to atoms place and there is ? at groups place. I had to edit again for every single assignment to bring the assignment table in proper shape. But when I saved the changes and re-open the project every thing had again messed up.

Can any one help me how can avoid this big headache

I would appreciate any ones positive response
