I tried importing png/svg/eps/ai files from illustrator into animate but it won't let me edit them

First, I tried to import a png file I had exported from illustrator and I put it onto my timeline in animate cc, but when I tried to erase/edit it didn't make any changes. In more detail, I would drag the eraser tool across my imported file and it would show the white lines being made, but when they disapeared the image was not affected. I am sure I was on the selected layer, so that is not the problem, I don't think. I also tried many other file formats to see if I could edit them. I tried png, svg, eps, ai, and jpg. But everytime I would try to erase it wouldn't let me do it. I also tried 'saving as' instead of exporting, but it didn't make a difference. I cleared up all the warnings when importing the file also. I just don't understand why I cannot edit the image that I have imported. For more clarification, the image I imported was made in illustrator and I drew it with the brush and pencil tools, it also was converted to live paint. I could really use some help, so please, I'm really desperate because this is driving me crazy. I feel like there is probably one thing I am doing wrong, but I just can't figure it out. So mainly, how should I export/import the file so that I can erase/edit it in animate, with a file created in illustrator?
