"Don't show this message again" box not working

When I receive the following message before running CCleaner Custom Clean and check the “Don’t show this message again,” the same message appears the next time I run the program. In other words, the “Don’t show this message again” checkbox is not functioning.

Hi @davezimny,
Thank you for reporting this issue, I was able to replicate this and have reported it to the development team to investigate.
If you have any questions, please message me back.
