TNF Bad behaviour With RIT on flex 6300 Smartsdr 1.9.9.9

Hi, all

Detected a problem with TNF Behaviour when using RIT. I tune in LSB 40m band a weak (S5) heterodyne signal, put a "Normal" depth TNF and kill the signal. I test it, moving VFO and almost no traces in audio of the offending signal can be detected. Come back VFO to the initial QRG and move RIT. I can hear the tone changing audio frequency when moving down and up. The tone remains after the tuning process. 

¿Can any of you try to reproduce this effect?

Best, Ni

I can confirm this unexpected behavior. Mode DIGU, TNF over a CW signal. Changing RIT brings the signal out from under the RF Tracking Notch Filter's influence. The TNF mark still looks good on the waterfall.

Seems 1.9.9.9 has been riddled with issues
Been on 1.8.4 and staying there.
Why?

I don't know about being riddled. 1.8.4 doesn't display this behavior?
