For nested item of group type with enable expression, in some case, answer is getting vanished for the item after packRepeatedGroups method while processing QR

To Reproduce
Steps to reproduce the behavior:

1. On Master branch apply the patch signs_complete_patch.txt
2. Run the app, Go to new questionnaire (+ icon n patient list)
3. Answer is not being rendered for the Respiratory rate
4. Undo the patch changes and apply this patch: signs_questionnaire_patch_mvp.txt
   list)
5. Now Re-run the app and again open the questionnaire, Interestingly it's working fine with MVP signs_questionnaire_patch_mvp.txt for the same item

Could you please remove any unnecessary characters from both the patch and attach separate questionnaire and questionnaire response files for the observed and not observed issues.

Thanks @santosh-pingle . Apologies for the delay. Here are the Questionnaires & QR (QR is same for both questionnaires)
The only difference in both questionnaires is of enableWhenExpression
signs_not_showing_respiratory_rate_questionnaire.txt
signs_not_showing_respiratory_rate_questionnaire_response.txt
signs_showing_respiratory_rate_questionnaire.txt

Patches:
not_working_signs.txt
working_signs.txt

The description mentioned that it should work for one questionnaire.json file, but I am not seeing the quantity value in either case. Can you please confirm?

[ppanchal-argus]

@santosh-pingle Can you try applying the working_signs patch directly? Ideally it should show this screen. Let me know if it's still not showing up.

[santosh-pingle]

yes, issue is observed on signs_not_showing_respiratory_rate_questionnaire.json.

This is for use on items of type integer and decimal

@khyativyasargus
Is the calculatedExpression extension truly necessary in signs_not_showing_respiratory_rate_questionnaire.json?

The questionnaire item in questionnaire.json has a calculated expression that returns an empty answer. This empty answer is then updated to the existing answer, which is why the text field shows nothing.

I don't Think so

I will remove it.

Thanks @santosh-pingle for looking up the cause. Really helpful!
