ADC DMA Interrupt Not Working STM32L152

Hi, I am working on a project using STM32L152. I have ADC DMA set up as I've used in many other projects using this part. For some reason this time around ADC values are not getting ready by the micro, and when I debug I find the DMA1_Channel1_IRQHandler is not getting called, even though the interrupt is set in the .ioc as normal. 

Here is my .ioc configuration for ADC and interrupt priority, is there anything here that can suggest what the problem might be? I have cross referenced these settings with other working hardware projects and they are exactly the same as far as I can tell. Thanks!

Please see attached screenshots for .IOC settings.

Does the DMA startup look alright?
