      0x68: variable

and this my resualts

Stumbled upon this also. Reading the webide code gave me come clues what us going on. As i understand this flags behavior is webide specific and is not part of generated code? can't find anything about it in the guide.

kaitai_struct_webide/src/v1/kaitaiWorker.ts

Lines 56 to 68 in a2496ac

	var flagCheck = 0, flagSuccess = true;
	var flagStr = Object.keys(enumObj).filter(x => isNaN(<any>x)).filter(x => {
	if (flagCheck & enumObj[x]) {
	flagSuccess = false;
	return false;
	}
	flagCheck |= enumObj[x];
	return obj & enumObj[x];
	}).join("|");
	//console.log(debug.enumName, enumObj, enumObj[obj], flagSuccess, flagStr);
	result.enumStringValue = enumObj[obj] || (flagSuccess && flagStr);

Yes, this is a misfeature of the Web IDE that doesn't respect how KS enums work. Currently, KS enums are strictly one-to-one bi-directional mappings between integer constants and identifiers (one integer value can be assigned to at most one identifier and one identifier can't be used more than once). The presence of an enum member is always based on equality - so an integer converted to an enum type matches at most one member in the enum.

@generalmimon Good to know. It confused me a bit as my case it only showed one enum name (no "|") so thought i had missed something how enums work.
