BMS settings went to zero on Overkill app

[Aussie]

I have 16s 280ah Rept cells with a JBD BMS and I replaced 4 of the cells and so I have had the high voltage overload shutting down charging ,but I noticed the cell was getting over 3.65 before shut off. I tried to change the settings and somehow they all went to zero. I am using the overkill app. Is there a default setting I can use or do I need to enter all new values? If I need to enter new values can I enter them all and then "write" or do I write after entering each value. If anyone can show me the values I need to enter that would be great.
Any ideas why the values all went to zero

No idea why, but after leaving everything alone overnight, all my values have come back.
