Themes, manually stored, i dont see on landing page edit/select list

Your software
My Mautic version is:2.16.2
My PHP version is:7.2.24

Your problem
My problem is:i downloaded some theme compatible with mautic. Try to upload thru Settings themes, but nothing do, themes doesnt uploaded. Ok, i think, i try to store theme directly on disk on /mautic/themes. I store all thems and next i see all themes stored on Settings/Themes. But, i dont see all themes when create a new landing or other, see only default themes.
What can i do ?

These errors are showing in the log:No errors into log file.

Steps I have tried to fix the problem:no steps, i dont know how fix.
