Here is what happens:
On Source Site Collection we have list with Title “Innovation Meetings” with custom field
Source list field
Id: f6737d18-f413-47df-a028-f07e7d2d8f94
StaticName: ExpirationDate
DisplayName: Expiration Date
Type: DateTime
and many more custom fields
When list is migrated all custom fields except the one mentioned above are migrated correctly
Instead of this 1 field above we remarked 2 additional fields – those do not exist in source list (it looks Metalogix mixed up things during migration):
Target list field 1
Id: 2139e5cc-6c75-4a65-b84c-00fe93027db3
StaticName: Date
DisplayName: Date
Type: DateTime
Target list field 2
Id: acd16fdf-052f-40f7-bb7e-564c269c9fbc
StaticName: _dlc_ExpireDate
DisplayName: Expiration Date
Type: DateTime
