Mitsubishi GX developer: setting "default" values....

[Mas01]

On our system, on the HMI we've got a page of setpoints. These are the values at which alarms are set (e.g. a high temperature alarm or a low water pressure etc). I updated the list to include D432, D433 & D434 in the same manner as the existing setpoints on the DEFAULTS page.
When the operator presses a "Reset to default" button on the screen (M72), the default values are applied (see picture). M72 is a momentary button and goes back to false.
All the setpoints (except mine) have the values expected at PLC power up. The operator can change these values at any time and can revert to the preset defaults by pressing the button.
For some reason, the ones I added are coming up as zero when PLC is first powered and only take the default values when the button is pressed.
How can I define D432, D433 & D434 so that (at PLC power up) they have the values shown in the picture?

Check if D432, D433 & D434 are within latch range.

Thanks, this is interesting. I've never looked at this page before. It appears that my D-registers are out-of-range.
Can I simply change 399 to say 450, for example?

Actually I think I should find some unused D-registers in the existing range. This is probably a safer option.

Update...I changed my original registers to be in the allowable range for latching, and it appears to be working now. When I cycle the PLC power, the value has been retained. Thanks for your help Tarik.
