Cannot set a BG target of 6.1, silent reset to 4 mmol/l

[widmann]

Trio is also affected by this bug:
Artificial-Pancreas/iAPS#712

If I try to set a BG target of 6.1 mmol/l in the UI, the setting is silently reset to 4 mmol/l after saving and exiting the UI. Setting 6.0 or 6.2 mmol/l works, so there is a workaround. However, since there is no visual feedback of the reset and a target of 4 mmol/l could have serious side effects, I would consider this a high priority issue.

Steps to reproduce:

• Open the target BG UI.
• Set a target of 6.1 mmol/l.
• Press save.
• Go back to Settings.
• Re-enter the target BG UI and find the target set to 4 mmol/l.

Expected result:

• BG target set to 6.1 mmol/l.

Actual result:

• BG target set to 4 mmol/l.

A prerequisite is probably setting the BG units to mmol/l, but I have not systematically tested this yet.

Summary

I confirm this issue exists with the most recent configuration for Trio-alpha.

Testing

• updated the latest alpha branch, commit 82f2d01
• built on existing Trio, SE running iOS 17.5.1
• set units to mmol/L
  • target was 99 mg/dL, now 5.5 mmol/L
  • modify target, save, go to settings, return to target screen:
    • choose 6.0; final 6.0
    • choose 6.1; final 4.0
    • choose 6.2; final 6.2

Did the same testing as Marion with the same outcome.

Can confirm this was the same with an older iAPS build (v2.2.5)

Yep, confirmed same in dev32b5e95 with pump simulator.
