Orders listing, Actions, Export a CSV file results in Class 'dbug' not found

-- HikaShop version -- : 4.6.0

If we go to Orders, and select an order (we are trying to select all monthly orders for the previous month, etc. but it doesn't matter what you filter on).

Then select items (all, or a single order).
Then Select Actions + Export as CSV File

Sometimes I can get results by unselecting specific fields, but it would be nice to trap this error to know what the cause is.

For example, on some orders I can select all fields without a problem. Then when I try to add fields to the selection list, the system throws this error.

I am trying to create a monthly sales detail report. This used to work when just using the EXPORT button, but now we lose order details...it only exports the order header information--not the order details. So I found this error while trying to find an alternative reporting scheme for the users.

Sure, here you go.

A little research I found that there is a dBug over on gitHub ( github.com/ospinto/dBug ) but the class is never loaded...but if I comment the two lines out that use that dbug command (2797-2798, it goes away

I see the class files, etc. but this is probably something left over from testing? The class is never included and dbug isn't used anywhere else.
