Order Export problem

CS-Cart Ultimate 4.16.1
When Exporting an order, in order to choose a different Export tab, like Order Items, a new layout needs to be created, and switched to before the EXPORT button displays.
On subsequent instances of the export, I have to switch to the other layout for the button to display.
So, two identical layouts are required for each tab - so I can switch between them to be able to display the EXPORT button.
I’m using an addon from Alt-Team that exports the order with the ordered items for import into ShippingEasy, and discovered that I have to switch between two different layouts for the Export button to display.
There seems to be some problem with the EXPORT button being hidden until a layout is selected if you switch to any other tab.
