Two plugins appear to have a problem with PHP7

Hello,

After starting a new project, two WPMUDEV plugins seem to have compatibility issues with PHP7. I have narrowed it down to this possibility because I have tried installing the same plugin on two identical WordPress sites with no themes or plugins installed - just Twenty Sixteen (the only difference is one site is scripted in PHP 5.6, the other in PHP 7.0.1).

I have attached two screenshots which might shed additional light onto the issue.
