Deco time wrong

Hello everyone,
I'd like to understand why when the computer reaches the decompression stops, it doesn't follow the indicated minutes but also significantly extends these times. For example, from 10 minutes at 6 meters, but in the end, almost 18/20 minutes pass.
I tried staying slightly below 6 meters (the meters number appear in green), I tried staying exactly at 6 by blocking it on a support, I tried staying slightly above (5), but in the end, it doesn't change.
Resetting its timer, I noticed that each minute actually passes at about 1:45/2 minutes.
If anyone knows the reason, thank you in advance.
PS: The setting is on full Bhulman without gradient factor (110/90) and computer is Ostc 2 tech

Why gases do you have set? It’s possible that you have gases set up that you are not using and the computer was expecting you to use them

Setting this as disabed or removing the switch depth will resolve this for you.

If you has gas enabled and the switch depth set then the computer assumes you are going to use these and shows you the deco time as if you were switching onto this other gas. If you keep the gas enabled but remove the switch depth then the computer will show you the deco schedule as if you were staying on your current gas and then if/when you do switch onto a richer gas then the deco time will reduce.
