Can't activate plugin even if dependencies are satisfied

[Jiedara]

Hi !
I'm currently making a project with wordpress were I need 5 hand-made plugin. I decided to make a "master" plugin and 5 "children" plugin, with dependancies.
I found your plugin to handle these dependancies, but I'm struggling to use it correctly. Or maybe I found a bug, I don't know yet...
French user here, sorry for my English and the screenshots, showing a french WP...

Well, my master plugin have
Provides: vdo_master
And my child
Depends: vdo_master
In their head commentary

The activation of masterplugin work well, but when I try to activate my child, plugin-dependencies throw this :

One or more plugins were not activated as their dependencies were not met at the time of activation. If the dependencies have been met in the mean time, please try and activate them again:
VDO Child

And under, WordPress display this to me

Plugin activacted

It's even more strange because in the plugin list, under my plugin name, I got

° VDO Master Plugin
Dependency : Satisfied

If you need more information, I'll be happy to help. Maybe I'm just making a stupid mistake ...

WordPress : 4.5.2
PHP : 7.0.3

Hi @Jiedara I'd like to try and help you, but I need more information to debug this properly.

Are you using the plugin on a single site or multi-site install ?
If multi-site, are you trying to activate on site or on the network ?
Which theme are you using and which other plugins have you got installed and which are active ?
Can I download the plugins somewhere to test with them myself ? Or if they are not online somewhere, would you be willing to mail them to me (just for testing) ?

I'm on single site, no theme installed (working with _s right now)

I got ContactForm7 and ContactFormDB and that's it.

Here an archive of my master and one of the child plugin :
