[Kovarex] [2.0.45] Blueprint parameter variables show error despite working

[Nova]

Create a blueprint with a parameter, for example a requester chest requesting a parameter 0 with amount 1. Set the blueprint parameter for the value 1 to a formula, for example p0_r*10+1.
Blueprint for that:

Copy blueprint


The parameter menu for the blueprint will show the input box in red with an error message:

But the blueprint itself will work just fine.
Writing a formula like pN_r*10+1 does show no error, but obviously doesn't work. (Because pN_r is no real variable, the N being a placeholder)

Seeing the same issue on 2.0.45 (same version). It confused the heck out of me
