[BUG] Only first 20 data stores are shown in dropdown of workflow step

**Describe the bug**
After adding more than 20 data stores, only those first 20 are selectable when adding a step to the workflow:

I do have a data store named transaction_payloads, however it says there are no matching options. When I go to data stores, the transaction_payloads store is on the second page.

**To Reproduce**
Steps to reproduce the behavior:
1. Add more than 20 data stores
2. Page to page 2 of the data store list (21st data store or after), grab that name
3. Create a new step in a workflow for a data store
4. Attempt to add that 21st data store name, says not found.

**Expected behavior**
Able to add any data store.
