Texture2D values and gradients are incorrectly appended in Alpha channel

After creating new material and inputting a texture coordinate node, and connecting with two mask nodes for R and G, then connecting to "Make Float 4" nodes, the values in the Alpha Channel don't match with the other material channels.

Results: Values for Alpha Channel differ from other channels
Expected: Values should be consistent across channels (i.e. the red mask value appended to the red channel should be the same as the one appended to the alpha channel)

• Open a new project and create new material.
• Open the material editor
• Make a texture coordinate node-connect it to two separate channel mask nodes for R and G values.
• Repeat the previous step so that the texture coordinate node is now connected to 4 channel mask nodes, 2 for the R channel, and 2 for the G channel.
• Connect all the values to a "Make Float 4" node
• Connect the Make Float 4 node to a "Debug Float 4 Values" node
