Rescue at baima and 1st 3 map bug. Can't get 3 star rating

[Bubblekia]

I have clear the map before the 2 week 1 day. Defeated boss with 0 troops death on 3 chillies, But I am unable get a 3 star rating for past 10 tries. Is is bug or what. The first 3 map all the same 0 deaths but can't get 3 star rating. Means I am unable get my red item reward forever because of this.

For a three star rating, you also need to finish the map in a certain time.
Rescue at Baima you need to finish in 2 weeks and 1day. Just click on achievements and then on three stars and you‘ll find the requirements

I tried finishing all first 3 maps with 3,4,5 star chillies within the time and 0 troop death. It just don't give me a 3 star rating for whatever I do. Something is wrong. It always give me 2 star. Even I clear much earlier. Please help developer its bug. Tell me what I did wrong.

Did you also have enough other fights (not only the boss fight) with no losses?
For example for Rescue at Baima you need 10 fights without losses to get three stars (and at least 3 chilies and maximum 2 weeks...)

I got threes stars in all maps, therefore I don’t think it’s a bug. But maybe sth changes, who knows...

Almatan, I tried clearing from start 0 troop death and it gives me 2 star rating still at the end. The developer doesn't reply and it sucks big time. I tried on all chilled and still same result. Nv once gave me a 3 star from 3-5 chilled with 0 troop death within the time frame. How can someone advise me. Super shitty
