Exported variable font doesn't work

I have a file with 26 masters (two for weight axis light and black and 24 for rotation axis). Exporting phase advances properly without any error message but the file only works in fontGoggles. It doesn’t work neither in mekkablue’s Variable Font Test HTML or other test tools.

I’m wondering if there is a limit on the number of masters?

Note: (3086) I have 24 rotation masters because we want to minimise the shrinking effect of linear interpolation.

Update: 3090, still exists.
