I do seasonality test in J-demetra. And I obtained seasonality problem in autocorralation test ac(12) and ac(24). how can I deal with this seasonality problem?

I upload the test results as a picture.

1. What is that you are doing that you see seasonality as a problem?
2. If I understand this correctly, you have data which (very) strongly rejects lack of seasonality on that first test, but not on any of the others. That sounds more like it's a data series which doesn't meet the underlying assumptions for those tests.
