Hi, is it just me or following is expected behaviour:

(1) lookupBestSeller:

Sample Response: “countProducts”: 30,
“products”: [
{
“position”: “#1”,
“salesMovement”: null,
“productRating”: null,
“countReview”: 0,
“url”: “/Gluten-Free-Air-Fryer-Delicious/dp/1837832439/ref=zg_bs_g_books_d_sccl_1/262-4934839-2947817?psc=1”,
“productTitle”: null,
“price”: 20.24
},
{
“position”: “#2”,
“salesMovement”: null,
“productRating”: “4.6 out of 5 stars”,
“countReview”: 152243,
“url”: “/Atomic-Habits-Proven-Build-Break/dp/1847941834/ref=zg_bs_g_books_d_sccl_2/262-4934839-2947817?psc=1”,
“productTitle”: null,
“price”: 7.53
},

	In the above response, 
	1. Title field is Null.
	2. First page in Amazon has 50 products; however only firsst 30 were returned.

(2) lookupProduct:

	Sample Response: 
	{

“responseStatus”: “PRODUCT_FOUND_RESPONSE”,
“responseMessage”: “Product successfully found!”,
“productTitle”: “Atomic Habits: the life-changing million-copy #1 bestseller”,
“manufacturer”: “by James Clear (Author)”,
“countReview”: 152245,
“answeredQuestions”: 0,
“productRating”: “4.6 out of 5 stars”,
…
…
“videoeUrlList”: [],
“productDescription”: null,
“productDetails”: [
{
“name”: “Publisher ‏ ‎”,
“value”: “Random House Business; 1st edition (18 Oct. 2018)”
},

		In the above response, 
		1. Product Description is Null
		2. Reviews that are pre-loaded on the page are pulled and not all.
		
		
(3) lookupReviews
		
		Amazon reviews page only show next and previous page buttons under listed reviews; however, query parameter requires page no.

Looking forward to some guidance.

Thanks!
