Is there a max number of configurations?

I've created a file with multiple configurations that are linked to an excel file.

Everything went smoothly when adding lines in the excel file, the changes would reflect correctly in the part file

and the new configurations created were added to the configuration tree.

After line number 62 in the excel file the new configurations are no longer showing up in the configuration tree.

When closing the excel file, after adding lines below line 62, SW correctly prompts for the addition of new configurations

without updating the configuration tree. Therefore, the new configurations are not accessible.

Is there a parameter setting I am missing, have I reached the end of Solid Works? Anyone experienced this little glitch before?
