Additional Information

added by @Versty

The description is not displayed for a newly added filter, but will be displayed when that filter is updated.

@DimitrisKalaboukas The title should not be updated because you enter it when adding the filter. But the description and version should be updated as you expecting. Clearly a bug, reproduces on our side as well.

@Versty Regarding the title, I agree in case it is entered or modified by the user. But, if it is auto-populated based on the filter list's "! Title: [...]" line, it should also be updated if modified by the list developer.

@Versty @maxikuzmin Auto-removal of removed filter list version info hasn’t been fixed. For example, in uBlock Origin lists an invalid “! Version: %version%” line is periodically being added for a short time (probably due to a bug) and then removed completely from the list, but not from AdGuard’s Custom filters info.
