Multi-volume archive: Size box acts weird in B7

[tvgeloof]

This may have been present in earlier beta's but I just noticed this on Beta 7.
Create a multi-volume archive. (RAR in my case).
The pop-up for the volume size is not showing whatever size you used the last time but a completely random number.
And the number changes each time you get into that box within the same TC session.

Looks like an uninitialized variable conaining random data is used to populate the input field.

Cannot reproduce. Can you tell me
1. whether you use Total Commander 32-bit or 64-bit
and
2. The exact Windows version (including Windows 10 version if you use that)?
