The flags in the unit_flags2 are the same as the unit_flags

**Describe the bug**
When using the set unit_flags2, the drop-down menu is the same as the unit_flags, but the unit_flags2 content in the parameters.json is different from the unit_flags

**Version (commit hash)**
Please include what was the WoW Database Editor version (commit hash). **If you downloaded binary, open file COMMIT_HASH from the main folder and paste the content in the issue description**

If you have built the binary yourself, check commit hash with `git rev-parse HEAD`

**To Reproduce**
Steps to reproduce the behavior:
1. Use creature script
2. Add any event
3. add set unit flag (18) or remove unit flag(19) action
4. type Select unit_flags_2 Select flags
5. What is real in the Flags menu is the content of Unitflag

**Expected behavior**
Displays the contents of the unit_flags_2

**Screenshots**
If applicable, add screenshots to help explain your problem.

Start by tracing the set unit_flags2 action's dropdown and compare its options with the unit_flags2 content in parameters.json. Reproduce the issue using a creature script and an event, then verify that selecting unit_flags2 displays its own flags rather than the unit_flags entries.
