issue with Autopropagation of numbers (Studio 2021)

Hi,

I have these numbers

1.000
2 000
2000 EUR
2000 USD
2000 €
2000 $
2 000

and they should be translated to this: (the spaces in target are narrow non-breaking spaces)

1 000
2 000
2.000 EUR
2.000 USD
2.000 €
2.000 $
2 000

translation starts fine but as soon as I confirm the 2nd segment, the 1st one gets replaced by 1,000 which makes absolutely no sense as target language (LB-LU) has no such number format set and TM does not contain such number string yet. Number recognition for TM is user defined for source and target number formats and all the above source numbers are set as correct number formats to be recognized)

Best regards,

Pascal
