check the raw tab on the color page. It may say 'decode using: camera metadata' so its applied to your footage
But if the raw tab says 'decode using: project' it applies the settings that are dialed in in your project settings in the RAW section. Those settings are not directly visible in the color page, so you easily could start to work with unwanted presets, by accident. Still you could change the raw settings for each clip to get them as log footage, but it is a good idea to set the project-raw-settings as you want them to have, at the first place
Sounds like you are used to debayer to a log format but now its set to 'Rec 709' in one of those raw sections.
