Inconsistencies translating the form between v3 and v4 of form builder

It seems some translations are not saved. Also, depending on whether we use the v3 translation options (warning message about missing translations gotten when we save the form in v3 editing) we get a more complete list of text strings to translate in this editor, than when using the Preferences menu on top, which looks like the v4 Settings options, and which misses several text strings to translate, available as per v3.

Also, it seems some of the widgets used in the form, like to create our schedule table, and on the first page of form the Academic experience options, is not featured in the elements to translate.

Please advise how to translate our form compeltely.

Thanks!

If you wouldn't mind letting us know what specifically is missing in V4 that is available in V3, we will be happy to have a look.  Everything available in V3 should be available in V4.  If anything is missing we can definitely add it back in.  The translations I did check in your form were working as expected:

Widgets function differently from regular fields and are not available for translation in the same manner.  For widgets like your table, you would need to create two different widgets, one for each language.  You could then show one or the other conditionally based on the the language selected:
