Confused About Reading null Values from the Database

I’m confused about what Wappler is supposed to do if a null value is read from the database and displayed in an input field via the dmx-bind:value="" parameter.

Should it display the word null?

Because that is what it is doing in my design (with Wappler 3.0.1), and when it is read into an input that relates to a number field it causes problems as the form is submitted each time - and looks rather strange that, for example, a field for Sales Tax has the value null.

I saw a post about this a month or so ago but cannot find it in the search now.

Am I right in saying Wappler should instead be displaying an empty input element when reading a null value?
