[Bug] ME:1 - LE - Hostile Takeover

Just like the last topic to this mission, I have found a bug in "Mass Effect 1 – LE" that prevents me to finish the mission "Hostile Takeover".

I've talked to Helena on the Citadel (this time without hacking the c-sec terminal) and killed both bosses, at first the (Hades - Dis – Klensal) captain and then the (Gemini – Han – Mavigon) one. However, the game still thinks that I only killed one of them.

I revisited both planets but it seems I looted everything and there aren’t any enemies. It's not the first time I played ME:LE but the first time I got this bug

Did anyone else found this bug and a way to fix it? I already tried to repair the game but it didn't help
