And when you encode the template then it gives no problem later? Just willing to understand/learn wh […]

As you can see, this template is marked 'private'. It's a common base for both ts_L1CTL_DM_EST_REQ_H0 and ts_L1CTL_DM_EST_REQ_H1, which are built on top of it (note the 'modifies' keyword below). The point is to have common fields initialized in the base template and initialize the 'h0h1' field in the child templates. TITAN warned us that 'h0h1' is missing in the template definition, but this is intentional, so in this patch we explicitly tell it that this field should remain uninitialized. The '-' in TTCN-3 is a bit like the undefined in JavaScript.
