Missing triggers in Reforged World Editor

[PraetorianSM]

Good time of a day!
Just tried that bright, stylish and fashionable Reforged WE (too old to these new things). Played around with new triggers, enjoyed with new functions and created some GUI triggers. Saved map and next day after... Half of them are just missing... They keep work in-game, but don't show up in the Editor. So, have anyone encountered this problem and can it be solved?
Thanks!
