Hi Chris and welcome back!
Have you checked to make sure your SQO instruction is not exceeding the amount of elements in the source array?
Check out my example image, since there is no position 10 in the sqo_test_source tag the data in the sqo_test_dest tag reads (2075180). This is basically garbage data. Care should be taken when setting up an SQO Instruction position, not to exceed the amount of elements in a Source array.
