Tune problem on 5973N

[Rick]

Hello!
I need you help.
The result of my autotune is mysterious.
The mass 69 give 420 000
The mass 219 give 148 000 (35% of 69)
The mass 502 give 15 000 (3.5% of 69)

Habitually, i have
69: 100%
219: 80 - 100%
502: 8 - 10%

My reppeler is high, 34.8 but my source is clean.

What do you think about this problem?

Thank you
