Weapon Release remapped?

[Sr.]

Recently, I switched my Steam setting for DCS to enable beta release...

 

 

 

Since then I cannot "fire" a Maverick missile (A-10C). I'll follow the same procedure I have been using... slew to target via the TGP screen, long press for SPI, SOI the mav screen then press the button I have mapped that makes the mav "auto slew" to the SPI, fine tune Mav slew to specific target, get the jiggle cursor, press release weapon button on my stick, mav screen goes black and the mav slew reticle immediately goes back to center of the HUD.

 

I have checked for cross mappings and the usual under controls etc.
