KSP 1.6, variant and deltaV glitch

[debug]

I recently got version 1.6 and I'm experiencing 2 glitches (updated from 1.4). 

1. The new part variants are not working. I select a desired variant but once I launch the vessel, it is reversed to the original 1.4 variant. This also occurs if I save the vessel and then reopen it. The issue is only with variants added in the two newest updates.

2. The deltaV is not accurately displaying. I have certain stages that have more than 0 deltaV but the readout still tells me that the burn time and deltaV is 0. Some stages (which include engines and should have deltaV) do not even have a deltaV amount displaying (i.e. they appear the same as in version 1.4) Once I stage the rocket to the stages that show no deltaV or 0, the deltaV pops up showing the correct value.

Any help is appreciated. Tell me if I should clarify anything.

1. Variant parts reverting to the old version is new to me.
I hope you have version 1.6.1 because the .1 fixed some (different) problems with the part database; you can download 1.6.1 from KSP store or wherever you bought the game, as it replaced 1.6.0 around 10 January.

Maybe someone else will recognize this. Maybe it will help if you spell it out: which part exactly and which variant ?

2. All of these problems with the delta-V readout are familiar to me.  The implementation is not very good yet. At least the display is either correct or obviously wrong.  It is a reasonable to continue to use the mod Kerbal Engineer Redux or the mod Basic Delta V until the main game repairs the bugs.

4 hours ago, debug said:

 version 1.6 [...] (updated from 1.4). 

That'll likely cause problem #1. Some of the file names changed between versions, so if you unpack 1.6 on top of 1.4, you'll end up with a mixture of the files from both versions. Just unpack 1.6 by itself, and then copy across your save games.

Sorry for the confusion. I'm already using 1.6.1.

I haven't checked all the parts yet but the issue is with the following:

FL-T200 fuel tank
FL-T400 fuel tank
Rockomax Brand Adapter 02

These parts do NOT have the issue:
Mk2 Lander Can
Aerodynamic Nose Cone

The issue is with all of the newest variants.

Thanks for the current help!

I'd still suggest exiting the game (not alt-f4, actually to through all the menus including confirming you wanted to exit on that 10th confirmation dialog box) and reloading. Just in case.

You don't say if you have it on Steam or not, but if so I'd suggest verifying the files. If not, I'd suggest installing it in a different folder and copying your save. If those don't work, verify the problem exists in a NEW save, perhaps (on Steam) uninstalling and wiping all local content, then reinstalling. After backing up your current save(s) of course.

Thanks, I'll give that a shot.

I've uninstalled KSP and then reinstalled it and that appears to have solved the issue. Thanks for everyone's help.
