Avar: Axis value map out of order

Hello, I am running into a consistent Fontbakery warn. I exported a variable font with Axis Location parameters set in all masters and active instances. I ordered the axes: wdth–wght–ital.
Upon export, I get:

ots-sanitize passed this file, however warnings were printed:

ERROR: avar: Axis value map out of order ERROR: Table discarded

When I remove the Axis Location parameters from the instance, this warn is no longer printed. What can I do to remedy this? Thanks!

It seems that the instance map to values are bigger or smaller than what the masters defines as the mapped space.
