Since it could be a data table issue, try Ctrl+N(reName) the client to something else (like "data_bad" or similar); this way THAT LINE of the data table is still there, it is just tagged as being kept out of your way.

Ctrl+A(dd) new client (try using a completely different Client #, in case that happens to be the trigger for the problem, like "test_new") and see if that one stays.

Then Ctrl+N(reName) that new one to the correct number.  (Or for paranoia: Ctrl+C(opy) it instead, so that you do not lose out on your data entry.)



Have you already done a CLPack?
