Different data in report in GUI and in API

I have weird situation. I want to print report with given ID. I checked ID on GUI and put it to this script. Everything looks fine, apart from vulnerabilities. On GUI I got correct vulnerabilites with severities and on script I got other (totally different than these from GUI) and all severites are 0.0. Maybe somebody knows what is wrong?

with Gmp(connection, transform=transform) as gmp:
    task1 = gmp.get_task(task_id)
    rep_id = task1.xpath('task/last_report/report/@id')[0]
    pretty_print(gmp.get_report(rep_id, details=True))

I add filter_strings="min_qod=80" and some of vulnerabilities have shown, but not all.
