When issuing an item in an Outbound Shipment, quantity does not update between switching measurements

[marthakeezy]

What went wrong? 😲

I have an item which I can issue in Doses, Packs or Packs of 2

For Doses and Packs, available quantity is 74, whereas Packs of 2 is 37

When I issue in Doses or Packs, Available and In Store quantities show correctly ✅
I switch to Packs of 2 -> Available and In Store quantities show halved which is also correct ✅
I switch back to Doses/Packs -> quantity does not update and stays halved 🚫
(Even though I can still issue the amount higher, so it's just the display that does not get updated)

Expected behaviour 🤔

Numbers should update promptly when switching between different measurements

How to Reproduce 🔨

Steps to reproduce the behaviour:

1. Have an item that you can issue in different ways, for example - doses, packs, packs of 2 like in my example
2. Go to Distribution -> Outbound Shipments -> new shipment
3. Add an item you are testing with -> note quantity when issuing in Doses/Packs (for example, 100)
4. Switch to Packs of 2 -> note quantity changed to half of whatever you had (for example, 50)
5. Switch back to original measurements -> note the quantity did not update
6. You can still issue the amount higher, as soon as you type in the quantity - display updates

@marthakeezy the drop down has doses/units/packs of 2 - but the description talks about doses/packs/packs of 2
the functionality is correct for displaying in doses and units - but the heading does not adjust for units, so that's misleading
as I see it the issue is this:

• The column heading doesn't update correctly when switching to the 'units' option
• The values are not updating when switching to either 'units' or 'doses'

if that's correct can you update the description please?
