Warning during OTA in Esphome (dev) latest version

I am working towards making a weighing scale using for load cells in bridge configuration using a green colored HX711 Amp board. I have made a link from E- to GND and soldered connector bases as shown in the pic. when I upload the code using OTA Iget a warning as below

The warning about obsolete PIO Core has been highlighted as strike through.
How do I remove multiple PIO cores as stated in this.

Did you read the link? What type of HA installation do you have?

@Troon, thanks for the response. Yes I did google multiple PIO cores, I was behind the cuve. I have Home assistant on a SD card with ESPhome (dev) as an addon. Platform IO is loaded where is not known to me. It is for this reason I have put up this querry here. Perhaps a more lucid approach will be helpful.

Best Regards…

I have the same warnings, on HA 0.112.2 and dev version of ESPHOME

Actually its in ESPHOME’s docs for setting up a SONOFF, guess its an old issue

There must be a way of removing duplicate files…
Many learned folks in the community. Will get a direction!

Wonder if it is only the dev version of esphome ?

It is in the normal esphome too. I changed to esphome dev in the hope that I would get rid of this but no luck, an issue has been raised but no luck yet.
