Why is AutoIt script toggling caps lock on and off when it runs

[SYNDAKIT]

Could anyone tell me why this script toggles caps lock on and off? 

Send("{ALTDOWN}{ALTUP}tel")
Sleep(800)
Send("{ALTDOWN}{ALTUP}{RIGHT}{RIGHT}{RIGHT}{RIGHT}{DOWN}{ENTER}")
Sleep(800)
Send("rel{SHIFTDOWN}-{SHIFTUP}model{SHIFTDOWN}-{SHIFTUP}name{ENTER}{TAB}{TAB}{TAB}{SHIFTDOWN}{HOME}{SHIFTUP}{CTRLDOWN}c{CTRLUP}{TAB}{SPACE}")
Sleep(800)
Send("{SHIFTDOWN}{TAB}{SHIFTUP}{SPACE}")
Sleep(800)
Send("{CTRLDOWN}o{CTRLUP}")
Sleep(800)
Send("{TAB}{TAB}{TAB}{CTRLDOWN}v{CTRLUP}.drw")

Try the following:

Opt("SendCapslockMode", 0)

Send("{CapsLock off}")
