Unable to merge tables in online PQE credentials

[JaromBIDEVatDK]

I have two tables that I want to merge. Both tables work fine individually and the credentials are signed properly for each individual table. However, when I go to merge its saying I am missing credentials. When I click the button to add credentials it just doesn't work. This is only happening on PQE online for a dataflow. PQE in desktop merges them without a problem. One table is an excel on a file server and the other table is a SQL table. I don't get the issue since both tables are find individually and only have issues when merging. I have tried merging and merging as new. I have also tried to flip the order that the merge takes place (Table 1 left join Table 2, Table 2 right join Table 1) None of these steps have worked. 

Any help will be super appreciated!

@JaromBIDEVatDK  try disabling the data load for everything except Merge and check this

It was the project option! It was turned off. Thank you so much.
