Discrepancies in variable parameters during Robyn model recreation

Hi Robyn team,

I am attempting to recreate a model that I previously saved using `robyn_write`, but I'm encountering an issue where the variable parameters don’t match the original ones. Both the saving and recreating processes are executed in the same environment with Robyn package version 3.11.1. Below are the code snippets I used:

### Save Model
```r
ExportedModel <- robyn_write(InputCollect, OutputCollect, select_model, export = TRUE)
print(ExportedModel)
```

### Recreate Model
```r
# Read original JSON
original_json <- robyn_read(json_file, quiet = TRUE)

# Recreate model
recreated_result <- robyn_recreate(json_file)

# Compare key coefficients
original_coefs <- original_json$ExportedModel$summary$coef
recreated_coefs <- recreated_result$OutputCollect$DecompAggs$coef

# Check differences
max_diff <- max(abs(original_coefs - recreated_coefs), na.rm = TRUE)
cat("Maximum coefficient difference: ", max_diff, "\n")

if (max_diff < 1e-10) {
cat("✅ Recreation successful! Coefficients are identical.\n")
} else {
cat("❌ Recreation failed. There are differences in coefficients.\n")
}
```

When recreating, the output shows:
```
>>> Recreating 3_382_3

I would appreciate any guidance on why the variable parameters aren’t matching and how to resolve this discrepancy. Thank you!
