The issue points to AnkerConfigDlg::handleDirtyPreset in AnkerConfigDialog. Read the dirty-preset branch and its callers to determine the intended return value when no dirty preset exists, then compare it with the stated save-preset requirement. Done means the function's return behavior matches that dialog flow rather than reporting an unconditional result.
