i created landingpagegrid with bodytext property then click on edit addded gridcontent as composition which is having samebodytext property in the gridcontent. it allows to save. now when i click on any document types am getting the same issue

ContentType with alias 'gridContent' was added as a Composition to ContentType with alias 'landingPageGrid', but there was a conflict on the following PropertyTypes: 'bodyText'. PropertyTypes must have a unique alias across all Compositions in order to compose a valid ContentType Composition.
