Usually the dot-dot-dot (known as an ellipsis) indicates the display is truncated and there is more actual data to follow.

What is your field type in the dissector for this data?

Since FT_BYTES items can be of arbitrary length these are indeed truncated to a certain length.

You can see the bytes in the value by selecting it in the tree and looking at the bytes highlighted in the hex pane.

If the value\packet is shorter than expected the dissector should have either detected that or there should be a malformed packet error when the dissector tried to access beyond the end of the packet.
