Bug: [REQUIREMENT].LEVEL vs AUTO_LEVELS

[mettta]

Adding the LEVEL: Level_0 parameter to the requirement gives an error when the server restarts:

error: [REQUIREMENT].LEVEL field is provided. This contradicts to the option [DOCUMENT].OPTIONS.AUTO_LEVELS set to On. Requirement: SDocNode(requirement_type = "REQUIREMENT", mid = NoneType(...), fields = [8 elements], relations = [1 elements], _tx_position = 34, _tx_position_end = 222, parent = SDocDocument(...), requirements = NoneType(...), has_meta = True, fields_as_parsed = [8 elements], ordered_fields_lookup = {8 elements}, ng_level = NoneType(...), ng_document_reference = NoneType(...), ng_including_document_reference = NoneType(...), ng_line_start = NoneType(...), ng_line_end = NoneType(...), ng_col_start = NoneType(...), ng_col_end = NoneType(...), ng_byte_start = NoneType(...), ng_byte_end = NoneType(...), context = SDocNodeContext(...), reserved_mid = "795170f3d30c41a6b67589662adab7f5", mid_permanent = False, ng_resolved_custom_level = "sdf", custom_level = "sdf", ng_whitelisted = True).

If added, but the server is not overloaded, the error does not appear.
