Removal of default task list while creating service order from repair order

Hi,

I have created a couple of operation items in task list group 7, counter 2 via tcode IA05 and IA06 and I want them to at least appear while I create service order from Repair order (by clicking Repair button and clicking Repairs check box in VA02). The above is for plant USA1.

However, I see that while I create service order, the default group is 6 and counter 1, which is maintained for plant IGD1, which is not my plant. How can I default the task list and operation lists that I have created? At least the ones I have created must be visible as an option to select, but that is also not happening.

Thanks in advance.
