Tracking bug?

I was unlocking hidden legion artifact bug, ebonchill, i found a good way to track the blue, green and purple colours, but not the red one,

the scripts i found was like this one but just the last number changed

/run C_ContentTracking.StartTracking(2, 11152)

I thought if i wanted the red one it was going to end with 1 since all the other three ended with 2, 3 and 4

The thing that happend was that in ahcievment tracking list all that show was a hyphen/minus sign -

now i want to get rid of that sign but havnt been able to find any info to get rid of it, for soon a week i have been trying and been talking with ingame masters, the last one i talked to, finaly understood my situation gave me a script that should stop tracking achievments but that didnt work, so now im here hoping to find a player with the knowledge to get rid of the -

It looks like this on my interface right side where the tracking is

All Objectives

quest

(whatever quest im tracking)

Achievments

-

Its that - i want to get rid of, ive tried all info that is on blizzard site, the normal delete/rename cache interface, shift/right click and bunch of other stuff i cant remember anymore.

Please let there be someone with knowledge how to get rid of it
