I have created a catalog, a schema and several tables within unity catalog, when I run a notebook that makes a merge to one of the tables the lineage of this is correct with all its dependencies, but if I run the notebook of another different table the lineage of the previous table is lost, apparently it is as if the lineage information is overwritten with the execution of each notebook. I am using a cluster with runtime 15.4. Can you help me if you can think what could be happening?
