It is impossible to assign a task to a team (via Resources module or Board module) if Team field is set to custom select and given select option contains any lowercase letter

Prerequisites:
N/A

Reproduction steps:

1. Create custom select field and specify its 2 options: "Software" and "HARDWARE" (notice lower and upper case in the names - this is important)
2. In App configuration of BigPicture, set created custom select as Team field
3. Create Program Box
4. Add 2 tasks to created Box: task 1 and task 2
5. Create 2 teams in created Box: first with code "Software", second with code "HARDWARE"
6. Navigate to Resources module of created Box
7. Assign task 1 to team "HARDWARE" and refresh the page
8. Assign task 2 to team "Software" and refresh the page

Actual result:

1. After refreshing the page, task 1 stays assigned to team "HARDWARE", but task 2 becomes unassigned again

Expected result:

1. After refreshing the page, both tasks stay assigned to their teams

Comments:

1. Although team "Software" was created with code written in the same case as select option "Software", BigPicture stores team code "Software" as "SOFTWARE". As a result, it further cannot match team code "SOFTWARE" with select option "Software". A solution to this issue is for BigPicture to compare team codes with select options in case-insensitive manner

Workaround:

1. Write all your select options with upper case (e.g., "SOFTWARE", not "Software" or "software"). Thanks to that, BigPicture will be able to match team codes (which are stored in upper case) with select options
