Not A Bug Bug Popular Egostist + Ultimely Malfunction

[Squall93]

Hi, my opponent used the triggered ability of Popular Egotist targetting me.
I used Ultimely Malfunction on the ability but the game said:

16:26: The target for Triggered ability from Popular Egotist cannot be changed.

I've lost for this reason

It says "target opponent". Targeting himself isn't a valid target.

You're right, thx
