[Bug Report] SigmaStudio Ver. 4.1, Build 1, Rev. 1761 - - Problem adding algorithm in first-order filter

A project developed in a previous, 3-point-something version of SigmaStudio had a bit of a hissy-fit opening in the installation of 4.1 that I'm running now. Warning messages on the screen could be bypassed and the project would open, but it would not compile and run. The opening messages cited single-order filters on two sheets of the project; one used as a low-pass, the other an all-pass. Both had been expanded into a 2-channel, stereo configuration with the Add Algorithm command. Replacing the 2-channel filter with two single-channel ones fixed the problem; the project then compiled and ran just fine.

Pulling a brand new single-order filter in off the Version 4.1 menu tree and expanding it to a 2-channel immediately brings up the same warning message on the screen, even before the filter is connected to anything. Here is a snapshot of the screen when this was done. The message is the same as the ones that previously popped-up when the old version of the file was loaded.

I have not run across this with other filters, and don't know whether it is typical only of designs initiated under a previous version of the program. But it's my story and I'm sticking with it.

Edit Notes
Fixed typo
