Label Pro not placing labels

For some reason LabelPro is not placing all labels from a layer.

If I apply no filter, it only places one of the available field data for a limited number of items.
If I apply the filter for the data I want, it gives me a no data to be placed message??

The object is more than long enough. 
To whit, the labels that do get placed, are for objects shorter than my target objects.
ie: it will place a label for an object that is 100m (real space) long, but not for an object that is 10,000(real space).

Any solutions?

  It sounds less like a length issue and more like a labeling rule or data issue.

  A few things worth checking:

  1. Scale range / visibility settings
  Make sure the layer doesn’t have a scale-dependent visibility limit applied. Sometimes labels won’t generate if the current zoom level is outside the defined labeling range.

  2. Expression / field type mismatch
  If you’re filtering for specific field values and getting a “no data to be placed” message, double-check:

  • The field name is correct (no hidden spaces or case differences).

  • The data type matches the filter (text vs numeric).

  • There are no null or blank values in the records you expect to label.

  Sometimes a filter works differently than expected if the field contains mixed data types or leading/trailing spaces.

  3. Label placement constraints
  Even if an object is long, the software may reject placement if:

  • The geometry has breaks or multipart segments.

  • The feature has invalid geometry.

  • The labeling engine considers it “too complex” at the current scale.

  Try simplifying the geometry or checking for multipart features.

  4. Conflict detection / overlap rules
  If label conflict detection is on, the engine may suppress labels it considers overlapping — even if visually there appears to be room. Try temporarily relaxing or disabling overlap restrictions to test.

  5. Projection / unit settings
  If your “10,000 real space” object is in a different projection or has unit inconsistencies, the labeling engine may not be interpreting its size the way you expect.
