As you are the only one reporting this problem it is probably related to your always pasting info in to the database.
When you do things this way the data does not get into the the headers of the files. When the database builds itself it gets the data from the file headers, you can't put the data into the headers from the database.
So I think you will always be running into problems of this nature.
If an extra field is added into Hosters database as can happen with updates as people request to have more info added your original file headers are outdated.
I can't see an easy way out for you although I am still puzzled why it should alter your book ids unless you have altered these manually by pasting into the database.
So for a small amount of time spent entering data when importing saves a lot of trouble later on. Also there have been big improvements in the Hoster edit dialog over the years making it possible to perform multiple edits.
