I recently acquired a Legacy #990 set. When checking the engine data base to clear any possible previous engine information, I found an entry for engine number 96, after unchecking the active engines only box. The only data fields completed are Control Type-Legacy and Sound type-Legacy Railsounds. There are no other fields with data.
The rest of the numbers available are completely blank except for my engine using number 1.
Is this default data of some type? If not, can I clear it? I only see other selections in the context box from the dropdown arrows. I'd like to clear if it is possible.
