bulb ramping issues on 6D

[seena007]

Hello everyone. I am new to the forum. I have ML on my t2i and bulb ramping works great. But on my 6D it doesn't work properly. I will set my correct exposure in M mode and then set the bulb ramping and intervolameter. When it starts up it takes the exposures  at 1" and does not ramp. Could someone please help me with this issue.

Thank you
