What does/doesn't work with the external definition?

Since this device came up as unsupported, I wrote an external converter for it.
This converter works very well at the Z2M device level (both controlling and getting the correct status from the panel).
But at the HASS level, status from the covers is wrong:
button pressed => reported activity (comment):
Down (close) => was closed (correct)
Down again (stop) => was opened (should be "was stopped")
Up (open) => No activity (should be "was opened").

I also tried a simple one-cover converter to try to isolate the problem, and it behaves the same: perfect at the Z2M level, but bad state at the HASS/MQTT device. The one-cover converter I used:

const tuya = require('zigbee-herdsman-converters/lib/tuya');
const exposes = require('zigbee-herdsman-converters/lib/exposes');

const e = exposes.presets;
const ea = exposes.access;

const definition = {
fingerprint: [
{
modelID: 'TS0601',
manufacturerName: '_TZE200_rgeapp2c',
},
],
model: 'TS0601_TZE200_rgeapp2c',
vendor: 'Tuya',

//options: [exposes.options.invert_cover()],
exposes: [
e.cover_position().setAccess('position', ea.STATE_SET),
],
meta: {
tuyaDatapoints: [
[1, 'state', tuya.valueConverterBasic.lookup({
OPEN: tuya.enum(0),
STOP: tuya.enum(1),
CLOSE: tuya.enum(2),
})],
[2, 'position', tuya.valueConverter.coverPosition],
],
},
};

module.exports = definition;

Notes

I would greatly appreciate your help with this.
Thank you

Start with the supplied external converter and the tuya.fz.datapoints, tuya.valueConverter.coverPosition, and cover-state converter entry points. Reproduce the close, stop, and open button actions, then trace how their states reach the HASS/MQTT device. Done means both covers report closed, stopped, or opened correctly at the HASS level.
