Can you provide a screenshot showing the result of Quickplace?  For example:

1. the source number is recognised (blue underline)
2. when I press Ctrl+comma the "translated" number is shown for me to place

Note that the comma is there.

Also note that subsequent numbers are automatically handled correctly from the TM and auto-propagated:

I used English to Korean for this.  So if you can provide more helpful information like this showing what you did, what the result actually was and what language pair you're using then we can provide a more helpful response.

korean -> japanese번역중이며,

다른 통역사들의 TM과, 구글 기계번역기를 걸어놓고 사용하고 있습니다.

아래 사진과 같이,

단위나 문자 없이 오직 숫자만 있는 세그먼트일때,

처음엔 [100%]상태이다가 

ctrl+enter로 다음 세그먼트로 넘어가는 과정에

아래쪽에 있는 숫자들이 자동으로 [CM]으로 번역되면서, 숫자의 ","가 사라집니다.

This doesn't seem to happen consistently as you're also showing 100% auto-propagated segments that have the comma as expected.

A CM match normally only gets this status if it is coming from your TM since it uses the value of the preceding target segment to determine whether it's a CM or a 100% match.  Since this value is only held in the TM I think you should find these segments in your TM and delete them.  Then I think it will work as expected.

I have tried to reproduce your issue and also tried to explain what I think is happening for you:

See if this helps you.
