Select field value not displaying the option that was previously saved

Using the Account form builder I’ve added a simple Select field with two values – see attached screenshot.

When testing this I have found that the value selected by the user is saved into the wp_uwp_usermeta table just as you would expect.

However when the user goes back to the account page the value shown is not the one they chose before – it is simply showing the first option on the list.

I’ve tested this with a select list that has only the display text (Option Values = blue,red,yellow,orange) and that works OK.

I’ve also tested it with a select list that has one-word display text and values (Option Values = car/1,bus/2,truck/3,lorry/4) and that is also OK.

Final test I did was also OK (Option Values = oneword/1,two words/2,three words here/3,four words go here/4)

So it seems to be something to do with the longer display text somehow triggering a bug so the saved option is not correctly displayed?
