Masking layer is gone when i export my project

I'm using Adobe animate 2019 here
i only have 1 mask layer in my project, under it are two classic tweening layers (both have blur filter on),i exported that and my mask layer is just gone
i converted my mask layers to symbol (movie clip) and the result is still mess up when exporting
i converted the 2 under layers as symbol too (from graphic to movie clip) and again its still mess up

everything looks normal in the program, its only mess up when i render it

In program

i tried to replicate the same layout on a new file and that exported fine so i don't even know anymore. Can anyone help?
