Problems with the light of the monitors

Recently after an update, my monitors are unable to maintain the light setting I put in. If I put it at 60% for example, if I restart the computer, turn it off, or turn off the monitors when I turn it back on is at 100% light. Would it be a problem relating to system updates? Has anyone experienced this?

what desktop manager you are using

Are you using an AMD GPU? This might be releated?
