negative bandwidth values for vertical video in the stream playlist

Hi! I'm streaming a video in a portrait orientation here is a link: https://customer-suqtc38zyv9qikx7.cloudflarestream.com/9d9d61e51c95ae74db424bfedbe8eab8/manifest/video.m3u8 and I get a playlist with negative Bandwidth values:

Negative values break some players on mobile clients. I know there was no such 'issue' a couple of days ago. Can you please confirm that it is not ok or normal? For streaming I use the latest OBS studio with a video output resolution 1080x1920. Thanks in advance for help.
