Roku remote increases volume by multiples of 2 or 3

We have been using a Roku Streaming stick with our Vizio TV since the TV was purchased in 2018. We also use a Vizio soundbar. We have used 2 different Roku Streaming Stick devices in the past with the Vizio TV and soundbar with no issues. No issues controlling the volume on the soundbar. The last Roku device needed to be replaced and the remote was not as responsive as it used to be.

I just purchased a new Roku Streaming Stick 4K 2021 which came with a new remote. I noticed this remote has issues controlling the soundbar. The volume will increase and decrease by multiples of 2 or 3. I tried pairing the remote with other Roku devices on other TVs and it works fine. However the volume issue continues with this Vizio TV and soundbar. 

I tried factory resetting the roku device and that did not fix the issue. I also purchased another new Roku remote hoping it would fix the problem. The volume issue continues with both new remotes.

This appears to be an issue with the newer remotes. I used at least 2 previous Roku remotes with our Vizio TV and soundbar with no issues. I also paired the old remote again and it controls the volume as expected. I can't keep using the old one as it has other issues. 

Any ideas how I can correct the volume issue. I have to keep the TV remote handy to control the volume. However I'd like to just use one remote like I did with the old Roku remotes. This appears to only be an issue with the newer Roku remotes with my Vizio TV and Vizio soundbar. No settings were changed.
