Power to kWh won't let me add to it after input change until its been idle for a while

So I changed some input names to more meaningful names coming from my server and I had no problems reassigning them to my existing feeds. That is until I tried adding my “Power to Kwh” type feed to the mix. It said that “this feed is already being written to, create a new one instead”, and I thought I would loose my history at that point. I went on here to search for other with the issue and I didn’t see anyone. So I went back to do the steps again so I could document a bug and it worked. So some time must go by before you can add the type of feed “Power to Kwh” to another input after removing it from the original input.
