Agree with Ravi. I created a choice field in my PDI with your same label and replicated this issue. What is happening is the element value on the choice is truncated because the column name is too long:
The choices are in the sys_choice table but since the element (column name) is truncated, they don't "sync" with the field:
So your quick solution is this:
1. Delete your current column
2. Create a new field called something like "Similar Issues"
3. Once created, then you can change the label back to your original. This will keep the database column name short
4. Then add the choices
Also please report this via Hi Incident because this is a defect that should be corrected. Please feel free to include a link to this thread but definitely explain the sys_choice element column is truncating and the choices aren't showing up as a result.
Once the choice field is on your form, right click on the label and choose Configure Choices:
