Synchronize dictionary - Application language Bug ??

Hello, I created a dictionary with a table.
I changed the label of table from {lang_tbl_bas_web_sitiWeb} to {lang_bas_web_sitiWeb} .
When I “Synchronize dictionary” with “Generate in language files with indexes of table fields labels?”, In the Application Language I found “Project Messages” - “tbl_bas_web_sitiWeb”.
Why ? This happens even when you change the label of a field. If I change a label of a field in the dictionary, in application language does not change.
