2. Start a clean profile offline. Make sure no alias/trigger/script/variable/timer defined
3. Create a script named 'test', paste code below and save to execute

if exists('mygroup', 'trigger') == 0 then
    permGroup('mygroup', 'trigger')
end
if exists('mytr', 'trigger') == 0 then
    permPromptTrigger('mytr', 'mygroup', '')
end
enableTrigger('mytr')
disableTrigger('mygroup')
debugc("isActive('mygroup', 'trigger')=" .. isActive('mygroup', 'trigger'))
enableTrigger('mygroup')
debugc("isActive('mygroup', 'trigger')=" .. isActive('mygroup', 'trigger'))

Error output / Expected result of feature

*** starting new session ***
[DEBUG:] isActive('mygroup', 'trigger')=0
[DEBUG:] isActive('mygroup', 'trigger')=0

Expected result: (in error view)

*** starting new session ***
[DEBUG:] isActive('mygroup', 'trigger')=0

Extra information, such as Mudlet version, operating system and ideas for how to solve / implement:

• Mudlet 4.14.1
• macOS 11.6
• x86_64

1. After steps above, switch to trigger view, the trigger group 'mygroup' shows with a bug icon.
2. Select the trigger group 'mygroup', the icon becomes locked icon.
3. Switch back to script view, the script would lead to correct result.
