Issue/Introduction

Steps to Reproduce: 
1- Go to Profile - Settings - General - Unit of Measure and set to "% Availability"

App-ca.log shows:

Other Units of Measure work fine
 
Expected Results: Able to expand resource to see allocations/assignments

Actual Results: Cannot expand resource to see allocations/assignments

Workaround: Use other units of Measure like FTE, Hours...
You can identify which users have this setting in Postgres with this
database query and ask them to use FTE or Hours.
The default setting is FTE

select user_NAME from cmn_sec_users
where id in (select user_id from cmn_ui_personalizations cup
-- for users using Percent Allocation...
where personalizations::json->>'units' = 'pct')
-- FTE
-- where personalizations::json->>'units' = 'fte')
-- hours
-- where personalizations::json->>'units' = 'hours')
