[Bug] Custom slash command appears duplicated and incorrectly highlighted in command selection menu

Bug Description
i have defined my custom slash command in user-wide setup and name it commit.md. but now everytime i type slash to do anything the custom command always shows up in the first order and often be in active state as if i am selecting it (in blue color text). even when i type for unrelated slash like i type "/usage" the /commit commands shows up twice like this

/commit Analyze changes and create atomic commits by logical unit, not by file. Use type: message format ... (project)
/usage Show plan usage limits and both the commit slash is in blue color which confuse me. but then if  i press enter the usage slash is the one selected tho
/commit Analyze changes and create atomic commits by logical unit, not by file. Use type: message format ... (project)
