Plug in not working on multiple symbols
**Which version of the plugin are you using?**
[X] Data Populator for Sketch. 3.0.3

**Describe the bug**
Am unable to use plug-in to populate symbol in my document. I have 2 symbols that are identical, copied from the one that works and pasted to another symbol.  The original symbols will populate, but the duplicate will not.  This was not an issue in the previous version of the plug-in as I noticed it.

**To Reproduce**
Steps to reproduce the behavior:
  
1. Select the top card and apply general_products_combo.json 
2. Data from JSON is applied in to the appropriate sections
3. Select card number 2 apply same JSON
4. Nothing happens


**Expected behavior**
I am expecting the cards to populate with my JSON data 

**Screenshots**
If applicable, add screenshots to help explain your problem.

**Environment (please complete the following information):**
 - macOS Version: [e.g. macOS Mojave 10.114.1]
 - Sketch Version [ Sketch 52.4] 
 - Plugin Version [e.g. 3.0.3]

**Additional context**
Before the latest update I was able to apply the plugin to my symbols with no issue.  After the update, I have noticed that it is not doesn’t work if I have multiple nested folders that the elements are located in. This is also when I have been experiencing the issue where the plug in was not replicating.  Again these are the exact symbols, I just changed the name of the symbol. So, one would think if it works for one it would work for the other. Not so.
