Validating drop-down fields not working on newer version v22.4, the appian is upgraded to v22.4

the latest version v22.4 seems to have a bug; 

The object identification fails for drop-down.

On New version 22.4 the element definition for dropdown is as below;

<span id="9d114c989f45ddbdab069168cd461dae_value_span">Value</span>

.Whereas for older version of appian the definition was as below;

<span id="4c85c14d61e4e58a2a354fc2a6e88f8d_selectedChoice" class="DropdownWidget---accessibilityhidden">Corporate</span>

the newest version (v22.4) of cucumber tries to find the object with the following Xpath;

//span[contains(@class, 'DropdownWidget---accessibilityhidden')]" 

This works on older version on newer version it fails
