Error using robyn_recreate() when there are NAs in a context variable (factor_vars)

Hi, I'm using Robyn v3.11.1 and I've encountered an unexpected behavior when trying to recreate a model using `robyn_recreate()`.
In my dataset (_raw_data.csv_), I have a context variable called _"context_promo"_ which I include as part of the `factor_vars` parameter in `robyn_inputs()`. This variable indicates the type of promotion for each week, but in some weeks there are no promotions, so the values are NA.

**Observed behavior**:
• When running the initial model using `robyn_run()` followed by `robyn_outputs()`, everything works fine. The model runs without errors and returns several valid solutions.
• However, when I try to recreate a specific model using `robyn_recreate()`, I get the following error:

> Error in check_nas(dt_input, c(paid_media_vars, paid_media_spends, context_vars, :
> Dataset structure(list(paid_google_search_impresiones = c(85827, 62459, contains missing (NA) values. These values must be removed or fixed for Robyn to properly work.

Since the original model runs without issues despite having NAs in the context variable, **shouldn't `robyn_recreate()` be able to handle the same data?
Could this be a bug in the `robyn_recreate()` function?**

**What is the recommended way to handle missing values in a categorical variable (factor_var) such as "_context_promo_"?** I can’t assign the value "_no_promo_" to the "_context_promo_" variable because Robyn would internally treat it as a different type of promotion, rather than as the absence of promotion.

Thanks in advance for your help! Let me know if you need more information.
