How to uncheck "Auto Delete Old Conversations" in storage settings??

Under Settings > Storage, I accidentally clicked "Auto Delete Old Conversations". I cannot uncheck the blue circle. How do I turn this feature off? I do NOT want to auto delete messages and attachments that are over 1 year old.

Under Settings > Messages, I have Message History set to Keep Messages: Forever. Does this counteract the above setting even though it is still shown as checked?

Seems absurd that you can't undo an opt-in feature or configuration, especially when gigabytes of personal data is at risk. Ridiculous.
