Neptune alk auto dosing

[DTz]

Hi, last nite I accidentally turned off my alk auto dose on apex fusion. Upon realising that this morning, I turned it back on to resume the auto dosing. It was set at 8 dkh. But was at 7.6 due to being off that nite. After 2 1/2 hours, I checked on the log and found out that it was auto dosing 200ml every 30 mins. And a total of 1 litre was dosed to my tank. Raising alk to 13 from 7.6. May I know what can cause this issue? I've been running trident control dosing for 8 mths and it's been doing fine all along. Here are some screen shots.

I’ve done it too bought caught it right away as I heard it kick on and not stop and grabbed the computer! I don’t trust it as much anymore.

Is your DOS tile on the dashboard set to AUTO, or did you set it to ON?

It was set to ON the 200mL is the tell tell sign and that the intervals were ever 30 minutes. When in the ON position it will run for 8 minutes and be off for 22 minutes.
