Answer 1

After debug and clearing all test data issue was still there.

After that I've disabled 3rd party modules and came to know that it's caused by Premium ERP. :(

Answer 2

Since I can't reproduce this in my system but I'm really curious what's up there, I stepped a little into the calculation of this field. Although this don't solve your problem, it might bring some light into the situation.

There are 3 values from which the salable quantity is calculated: The quantity in stock (which is the sum of all sources of the stock), the reserved quantity (from orders) and the configured minimum quantity.

The formula is: quantity in stock + reserved quantity - minimum quantity

With this SQL statements you can check the situation in your database:

-- quantity in stock
select quantity from inventory_stock_[YOUR_STOCK_ID] where sku = '[YOUR_SKU]';

-- reserved quantity
select SUM (quantity) from inventory_reservation where sku = '[YOUR_SKU]';

-- configuration for minimum quantity in stock
select min_qty, use_config_min_qty from cataloginventory_stock_item 
where product_id = (select entity_id from catalog_product_entity where sku = '[YOUR_SKU]');

Please run this statements for your product and share the results with us.
