Colors Exchange effect is permanent, not 1 time-only

[ldd2]

Greetings buddies.

For a long time, I used GIMP v2.10.2 as it was fitting needed requirements for some pixel art files.

I recently have installed most updated GIMP version and got an issue with Color tab > map > Colors exchange

Issue is, in older GIMP version, i used this feature to exchange a couple of pixels with another color from same Color map file (256 indexes only). 

In most updated version, I use same feature and e.g: I switch color index 175 with index 230, all pixels with that color get an exchange. 
The issue here is that this effect is Permanent, and I dont know how to stop that from happening.
In older GIMP version, this effect was just 1 time for this colors exchange. In newer version, if involved Pixels get colors exchange effect, then if I try to use e.g: Index 175, it will paint any next pixel with Color that I used for Color exchange. e.g: index 230, besides i'm selecting index 175.

Thanks, in case can bring help.

idd2: Hi! By default in GIMP 3+, filters are non-destructive. They "float" above the layer, and you can go back and edit them. If you want them to be destructive, you can do a few things:

1) Click on the "Fx" icon next to the layer in the layer dock and click the "Merge down" icon
2) Make sure the "Merge filter" checkbox is checked in the filter dialogue before you click Okay. This setting should be remembered.

Done, thank you a lot for your kind help, friend.
