I didn’t find any straight across 55 to 55 rings.
As I understand it, since your lens has an external 55mm thread as would normally be found on a filter (i.e. a male thread) you require a female to female adapter which when attached will in effect turn your lens thread into a "normal" lens which will take any filter having a male thread.
I made a mistake in my post below and wrote that you need a female to male adapter where in fact you need a female to female adapter. Your filters will then screw on without reversing them.
Sorry it's somehow hard to get my head around this I guess because I have not come across it before and I momentarily could not visualize what was needed.
But the adapter you need appears to be exactly - this one
Will it screw on correctly to your lens given you seem to be saying this has also been an issue peculiar to that lens. Well that's the question I cannot answer but it should if your lens uses the same thread pitch as all other lens threads. Bear in mind that a filter's threads do not have to "screw in all the way" so long as the end of filter thread cinches up tight inside of the lens and the filter becomes tight.
