Creation of a specific channel not done importing a list of channels

I restart the proxy server,
Then I import several times an input csv file and only one over 14 channels have not been opened (we cannot see it in the list of channels), but it exists in the persistent file.
We finaly have to restart the proxy server to fix the problem, and the channel appears (like it's a persistent channel). Then the import was correct and contains all the 14 channels.

In attachment, the channels before the 1st restart, the channels after the restart and without the 10010 channel. The input csv file
