A non-working/empty file is saved

[soultear]

An empty/non-working file is saved/exported. I tried to check how it works for RPG Maker MZ. I took the finished effect and immediately saved this animation under a different name in the same folder. However, I don't see anything in the RPGM editor. There is no my animation. I checked a few animations - nothing. I'm watched the videos, and everything is fine there, people change colors and other things and just save, then connect the effect in the editor.
What can be wrong?
Version 1.70b

All effects work great in Effekseer:

Did you install EffekseerForRPGMakerMZ_Ex
RPGMakerMZ doesn't support 1.7 without the plugin.
