Issues with 533MC Pro image calibration and stacking artifacts

Hello, I am new to deep sky processing, and have some odd blocks appearing in my image.
This is a capture of M45, about ~1 hour of data with 5 min exposures and with a few of the images drizzled. I stacked using deep sky stacker on the recommended settings, and am using PixInsight. Data collected on an ASIair plus.  This image does not have calibration files, as those are also causing me more issues than not, at the moment.

When zooming in, I can see these strange looking blocks, after splitting the colors, linear fit and channel combination.  
Would appreciate any ideas here. Thanks!

I added drizzle 2x to the imgaes, and it looks like it fixed the issue!
