DataSource.NotFound: SharePoint: Request failed (404)... for only one column

Hello,

Getting data from a SharePoint List Online, I get all the columns fine and valid except for one:

DataSource.NotFound: SharePoint: Request failed (404): The remote server returned an error: (404) Not Found. (Cannot find resource for the request OData__x0031__x002e__x0020_BDM_x0020_i.)
Details:
    DataSourceKind=SharePoint
    DataSourcePath=https://arcelormittal.sharepoint.com/sites/AMTB-Operations/RFQ%20WF%20Std
    SPRequestGuid=1273619f-8081-2000-5ed7-2ff9dba8aa23
    Url=https://arcelormittal.sharepoint.com/sites/AMTB-Operations/RFQ WF Std/_api/Web/Lists(guid'6d66f7f0-ea5c-4dfe-b045-fef32113fcdb')/Items(15)/OData__x0031__x002e__x0020_BDM_x0020_i

 Another column has an error but I don't care, it's the 'Versions' one:

DataSource.Error: We couldn't parse OData response result.  Error: A value without a type name was found and no expected type is available. When the model is specified, each value in the payload must have a type which can be either specified in the payload, explicitly by the caller or implicitly inferred from the parent value.

Thank you beforehand for your help -
