What could be causing my processes to fail the second time using Vue?

In my Vue application, I have a parent component that contains several nested components. Initially, I retrieve product data from the database and perform calculations using Vue on the elements stored in an array.

Everything works fine the first time, but the second time, my data is not reactive. When I check the console with Vue Devtools, I can see that the property changes, but it doesn't reflect on the screen.

What could I be doing wrong? At the end of the first iteration, I reset the values of the elements in the `data(){}` method like this:

 this.showModalOptions = false;
this.showModalType = false;
this.updatePrices = false;
this.products = [];
this.productsSelect = [];
this.productSelect = {};
this.type = {};
this.fetchProducts(); // Fetch products and assign them to the 'products' array

Method fetchProducts:

 fetchProducts(){
        axios.get('/api/products/all')
        .then((result) => {
            this.products = result.data.products;
        });
    }

Data declaration:

data() {
        return {
            products: [],
            productSelect: {},
            type: {},
            productsSelect: [], 
            showModalOptions: false,
            showModalType: false,
        };
    }

I'm unable to provide a working example, but I suspect that resetting the array or objects may be causing them to lose reactivity. Any suggestions?

Considering your suggestion, in case the property undergoes modifications while the screen remains static, it might be beneficial to experiment with either vm.$forceUpdate() or vm.$nextTick(yourFunction) to update the event queue.
