[Workflow] Nested workflows overwriting global table

[n1xn]

Describe the bug

Online-shop > Categories > Sub-Categories > ProductList > ProductDetails

Setting up a workflow for each step, in sum 5. Each workflow has a loop to extract data and pass it to the next via variables. The last workflow has now all data and is inserting into global table. When all loops are done the first workflow should export this data to CSV. The problem is that every new loop iteration higher then ProductDetails is resetting the global table.

Expected behavior

Don't overwrite the global table or have the ability to pass data up in hierarchy.
