Translaion Memory(TM): translation units newly added to TM are not always added to the end of the TM?

Hello everyone. This is my first post. I would appreciate it if you could help with my issues. 

1. This is what I have tried:

       In the final process of translation, I confirmed each translation unit on the Editor View and added it to a TM. Next I went to the Translation Memories View and opened the TM.  

2. This is what happened:

      A) The newly added translation units are scattered across the TM, meaning they can have Traslation Unit Id 10, 55, 110, and 200-205, for instance. 

      B) Some of the newly added translation units are invisible on the Translation Memories View. I have confirmed all the translation units have been successfully added to the TM, using the source text column.

3. I would like to achieve:

    A) Is there any rules or settings to determine the order of translation units in the Translation Memories View? If so, please show me how to change the settings.

    B) Is there any way to visualize all the translation units in the TM? 

Thank you very much for your help in advance.
