themes disappeared

when i go to network > themes > there are 10 themes showing
lets call them 1-10

when i check my server wp-content/themes folder there are 15 themes in there we will call those 1-15

i have sites using all themes 1-15

the sites using themes 11-15 work fine but again the themes 11-15 are not shwing up in network > themes all themes

when i go to a site that is using one a theme 11-15 and go to appearance > themes i see this...

current theme

is all that shows... my styes.php file has a theme name and author so it should be showing it?

the screenshot.gif file is also installed so that isnt showing.
