CSV version commit of translations is adding header info source, target

### Describe the issue

When i read csv files from our project the csv files do not contain the header source, target. When i modify translations and commit them to our repository Weblate add's the header "source", "target" which is not the original state. I cannot disable this setting. I use file format "CSV File" which if i understand the documentation correctly should be headerless.
