The value street-address cannot be used for attribute autocomplete on an <input> element. As this kind of autofill is oriented for multi-line inputs (as in the expected format for addresses), consider using a <textarea> element instead, like in this example:

<textarea name="address" autocomplete="street-address"></textarea>

The value tel-national cannot be used on the attribute autocomplete of an <input> element of type tel. Either change to type="text", or use autocomplete="tel". Examples:

<!-- Using autocomplete "tel-national" on type "tel" is invalid -->
<input name="phone1" type="tel" autocomplete="tel-national" />

<!--Using autocomplete "tel-national" on type "text" is valid -->
<input name="phone2" type="text" autocomplete="tel-national" />

<!--Using autocomplete "tel" on type "tel" is valid -->
<input name="phone3" type="tel" autocomplete="tel" />
